Unleashing the Power of Customer Data Platforms (CDPs) and AI: A Game-Changer for Modern Marketing

For some unknown reason, my last three presentations all started as headlines (two created by someone else) which I then then wrote a speech to match. This isn’t my usual way of working. It does add a little suspense to the writing process – can I develop an argument to match the title? It also dawns on me that this is the way generative AI works: start with a prompt and create a supporting text. That’s an unsettling thought: are humans now imitating AI instead of the other way around? Or have I already been replaced by an AI but just don’t realize it? How would I even know?

The latest in this series of prompt-generated presentations started when I noticed that the title shown in a conference agenda didn’t match the speech I had  prepared. When I pointed this out, the conference organizers said I could give any speech I want, but the problem was, I really liked their title: “Unleashing the Power of Customer Data Platforms (CDPs) and AI: A Game-Changer for Modern Marketing”. 

The idea of “unleashing” a CDP to run wild and exercise all its powers, is not something I get to talk about very often, since most of my presentations are about practical topics like defining a CDP, selecting one, or deploying one. And I love how “and AI” is casually tucked into the title like an afterthought: “there’s this little thing called AI, perhaps you’ve heard of it?”

And how about “game changer for modern marketing”? That’s an amazing promise to make: not just will you learn the true meaning of modern marketing, but you'll find how to change its very nature so it’s a game you can win. Who wouldn’t want to learn that?

This was definitely a speech I wanted to hear. The only problem was, the only way for that to happen was for me to write it. So I did. Here’s a lightly modified version.

Let’s start with the goal: winning the modern marketing game. The object of the game is quite simple: deliver the optimal experience for each customer across all interactions. And, when I say all interactions, I mean all interactions: not just marketing interactions, but every interaction from initial advertising impressions through product purchase, use, service, and disposal. I also mean every touch point, from the Internet and email through call centers, repair services, and the product itself.

That’s a broad definition, and you will immediately see the first challenge: all the departments outside of marketing may not want to let marketing take charge of their customer interactions. Nor is your company’s senior management necessarily interested in giving marketing so much authority. So marketing’s role in many interactions may be more of an advisor. The best you can hope for is that marketing is given a seat at the table when those departments set their policies and set up their systems. This requires a cooperative rather than a controlling attitude among marketers.

The second challenge to winning at marketing is the fragmented nature of data and systems. Most marketing departments have a dozen or more systems with customer data; at global organizations, the number can reach into the hundreds.  Expanding the scope to include non-marketing systems that interact with customers adds still more sources such as contact centers and support websites. Again, marketing will rarely control these. At best, they may have an option to insert marketing recommendations directly into the customer experience, such as suggesting next best actions to call center agents.

The third challenge is optimization itself. It’s not always clear what action will result in the best long-term results. A proper answer requires capturing data on how customers are treated and how they later behaved as a result. Some of this will come from non-marketing systems, such as call center records of actions taken and accounting system records of purchases. Again, those systems’ owners may not be eager to share their data, although it’s harder for them to argue against sharing historical information than against sharing control over actual customer interactions.

But the challenge of optimization extends beyond data access. Really understanding the drivers of customer behavior requires deep analysis and no small amount of human insight. Some questions can be answered through formal experiments with test and control groups. But the most important questions often can’t be defined in such narrow terms. Even defining the options to test, such as new offers or marketing messages, takes creative thought beyond what analysis alone can reveal.

And even if you could find the optimal treatment in each situation, the playing field itself keeps shifting. New products, offer structures, and channels change what treatments are available. New systems change the data that be captured for analysis. New tools change the costs of actions such as creating customer-specific content. These all change the optimization equation: actions that once required expensive human labor can now be done cheaply with automation; fluctuating product costs and prices change the value of different actions; evolving customer attitudes towards privacy and service change the appeal of different offers. The optimal customer experience is a moving target, if not an entirely mythical one.

None of this is news, or really even new: marketing has always been hard. The question is how “unleashing” the power of CDPs and AI makes a difference.

Let’s start with a framework. If you think of modern marketing as a game, then the players have three  types of equipment: data systems to collect and organize customer information; decision systems to select customer experiences; and delivery systems to execute those experiences. It’s quite clear that the CDP maps into the data layer and AI maps into the decision layer. This raises the question of what maps into the delivery layer. We’ll return to that later.

First, we have to answer the question: Why would CDP and AI be game changers? To understand that, you have to imagine, or remember, life before CDP and AI. Probably the best word for that is chaos. There are dozens – often hundreds -- of data sources on the data layer, and dozens more systems making choices on the decision layer. The reason there are so many decision systems is that each channel usually makes its own choices. Even when channels share centralized decision systems, those are often specialized services that deal with one problem, whether it’s product recommendations or churn predictions or audience segmentation.

CDP and AI promise to end the chaos by consolidating all those systems into one customer data source and one decision engine. Each of these would be a huge improvement by itself:

  • the CDP makes complete, consistent customer data available to all decision systems, and
  • AI enables a single decision engine to coordinate and optimize custom experiences for each individual.

Yes, we’ve had journey orchestration engines and experience orchestration engines available for quite some time, but those work at the segment level. What’s unique about AI is not simply that it can power unified decisions, but that each decision can each be tailored to the unique individual. 

But we’re talking about more than the advantages of CDP and AI by themselves. We’re talking about the combination, and what makes that a game-changer. The answer is you get a huge leap in what’s possible when that personalized AI decisioning is connected to a unified source of all customer information. 

Remember, AI is only as good as the data you feed it. You won’t get anything near the full value of AI if it’s struggling with partial information, or if different bits of information are made available to different AI functions. Connecting the AI to the CDP solves that problem: once any new bit of information is loaded into the CDP, it’s immediately available to every AI service. This means the AI is always working with complete and up-to-date data, and it’s vastly easier to add new sources of customer data because they only have to be integrated once, into the CDP, to become available everywhere.

To put it in more concrete terms, one unified decision system can coordinate and optimize individual-specific customer experiences across all touch points based on one unified set of customer data. 

That is indeed a game-changer for modern marketing, and it only reaches its full potential if you “unleash” the CDP to consolidate all your customer data, and “unleash” the AI to make all of your experience decisions.

That’s a lot of unleashing. I hope you find it exciting but you should also be a little bit scared. The question to ask is: How can I take advantage of this ‘game changing potential’ without risking everything on technology that is relatively new and, in the case of AI, largely unproven. Here’s what I would suggest:

Let’s start with CDP. So far, I’ve been using the term without defining it. I hope you know that a CDP creates unified customer profiles that can be shared with any other system. No need to get into the technical details here. What’s important is that the CDP collects data from all your source systems, combines it to build complete customer profiles, and makes them available for any and every purpose.

Some people reading this will already have a CDP in place but most probably do not. So my first bit of advice is: Get one. It’s not such easy advice to follow: a CDP is a big project and there are dozens of vendors to choose from, so you have to work carefully to find a system that fits your needs and then you have to convince the rest of your organization that it’s worth the investment. I won't go into how to do that right now. But probably the most important pro tips are: base your selection on requirements that are directly tied to your business needs, and ensure you keep all stakeholders engaged throughout the entire selection process. If you do those two things, you can be pretty sure you’ll buy a CDP that’s useful and actually used.

That said, there are some specific requirements you’ll want to consider that tie directly to ensuring your CDP will support your AI system. One is make sure you buy a system that can handle all data types, retain all details, and handle any data volume. This does NOT mean you should load in every scrap of customer-related data that you can find. That would be a huge waste. You’ll want to start with a core set of customer data that you clearly need, which will be data that your decision and delivery systems are already working with. This lets the CDP become their primary data source. Beyond that, load additional data as the demand arises and when you’re confident the value created is worth the added cost.

The second requirement is to ensure your CDP can support real time access to its data. That’s another complicated topic because there are different kinds of real time processes. What you want as a minimum is the ability to read a single customer profile in real time, for example to support a personalization request. And you want your CDP to be able to respond in real time to events such as a dropped shopping cart. Your AI system will need both of those capabilities to make the best customer experience decisions. What’s not included in that list is updating the customer profiles in real time as new data arrives, or rebuilding the identity graph that connects data from different sources to the same customer. Some CDPs can do those things in real time but most cannot. Only some applications really need them.

The third requirement relates to identity management. The CDP needs to know which identifiers, such as email, telephone, device ID, and postal address, refer to the same customer. At CDP Institute, we don’t feel the CDP itself needs to find the matches between those identifiers. That’s because there’s lots of good outside software to do that. We do feel the CDP needs to be able to maintain a current list of matches, or identity graph, as matches are added or removed over time. That’s what lets the CDP combine data from different sources into unified profiles.

My second cluster of advice relates to AI. I’d be surprised if anyone reading this hasn’t at least tested ChatGPT, Bing Chat Search, or something similar. At the same time, there’s quite a bit of research showing that relatively few companies have moved beyond the testing stage to put the advanced AI tools into production.

And that’s really okay, so my first piece of advice is: don’t be hasty.  You should certainly be testing and probably deploying some initial applications, but don’t feel you must plow full speed ahead or you’ll fall behind. Most of your competitors are moving slowly as well. 

That said, you do need to train your people in using AI. They don’t necessarily need to become expert prompt writers, since the systems will keep getting smarter so specific prompting skills will become obsolete quickly. But they do need to build a basic understanding of what the systems can and can’t do and what it’s like to work with them. That will change less quickly than things like a user interface. The more familiar your associates become with AI, the less likely they are to ask it to do something it doesn’t do well or that creates problems for your company.

Third, pay close attention to AI’s ability to ingest and use your company’s own data. Remember the game-changing marketing application for AI is to create an optimal experience for each individual. The means it must be able to access that individual’s data. This is an ability that was barely available in tools like ChatGPT six months ago, but has now become increasingly common. Still, you can bet there will be huge differences in how different products handle this sort of data loading. Some will be designed with customer experience optimization in mind and some won’t. So be sure to look closely at the capabilities of the systems you consider.

Fourth, and closely related, the industry faces a huge backlog of unresolved issues relating to privacy, intellectual property ownership, security, bias, and accuracy. Again, these are all evolving with phenomenal speed, so it’s hard for anyone to keep up – even including the AI specialists themselves. Unless that’s your full time job, I suggest that you keep a general eye on those developments so you’re aware of issues that might come with any particular application you’re considering. Then, when you do begin to explore an application, you’ll know to bring in the experts to learn the current state of play.

Similarly, keep an eye on the new capabilities that AI systems are adding. This is also evolving at incredible speed. Some of those capabilities may change your opinion of what the systems can do well or poorly. Some will be directly relevant to your needs and may form the basis for powerful new applications. We’re still far away from the “one AI to rule them all” that will be the ultimate game-changer for marketing. But it’s coming, so be on the alert.

This brings us back to the third level of marketing technology: delivery. Will there be yet one more game-changer, a unified delivery system that offers the same simplification advantages as unified data and decision layers? The giant suite vendors like Salesforce and Adobe certainly hope so, as do the unified messaging platforms like Braze and Twilio. The fact that we can list those vendors offers something of an answer: some companies think a unified delivery layer is possible and would argue they already provide one. I’m not so confident because new channels keep popping up and it’s nearly impossible for any one vendor to support them all immediately.

What seems more likely is a hybrid approach where most companies have a core delivery platform that handles basic channels like email, websites, and advertising and supports third-party plug-ins to add channels or features they do not. These platforms are already common, so this is less a prediction of the future than an observation of the present, which seems likely to continue. The core delivery platform offers a single connection to the decision layer run by the AI. This gives the primary benefits gained from a single connection between layers, although I wouldn’t call it a game-changer only because it already exists.

My recommendation here is to adapt the delivery platform approach, seeking a platform that is as open as possible to plug-ins so it can coordinate experiences across as many channels as possible. In this view, the delivery platform is really an orchestration system. Which channels are actually delivered in the delivery platform and which are delivered by third-party plug-ins is relatively unimportant from an architectural point of view.  Of course, vendors, marketers, and tech staff will all care a great deal about which tools your company chooses.

While we’re discussing architectural options, I should also mention that the big suites would argue that data, decision, and delivery layers should all be part of one unified product, reducing integration efforts to a minimum. That may well be appealing, but remember that most of the integrated suites were cobbled together from separate systems that were purchased by the vendors over time. Connecting all the bits can be almost as much work as connecting products from different vendors.

And, of course, relying on a single vendor for everything means accepting all parts of their suite – some of which may not be as good as tools you could purchase elsewhere. The good news is most suite vendors have connectors that enable users to use external systems instead of their own components for important functions. As always, you have to look in detail at the actual capabilities of each system before judging how well it can meet your needs.

So, where does this leave us?

We’ve seen that the object of the modern marketing game is to deliver the optimal experience for each customer. And we’ve seen that challenges to winning that game include organizational conflicts, fragmented data, and fragmented decision and delivery systems.

We’ve also seen that the combination of customer data platforms and AI systems can indeed be game-changing, because CDPs create the unified data that AI systems need to deliver experiences that are optimized with a previously-impossible level of accuracy.

CDPs and AI won’t fix everything. Organization conflicts will still remain, since other departments can’t be expected to turn over all responsibility to marketing. And fragmentation will probably remain a feature of the delivery layer, simply because new opportunities appear too quickly for a single delivery system to provide everything.

In short, the game may change but it never ends. Build strong systems that can meet current requirements and can adapt easily to new ones. But never forget that change is inherently unpredictable, so even the most carefully crafted systems may prove inadequate or unexpectedly become obsolete. Adapting to those situations is where you’ll benefit from investment in the most important resource of all: people who will work to solve whatever problems come up in the interest of your company and its customers.

And remember that no matter how much the game changes, the goal is always the same: the best experience for each customer. Make sure everything you do is has that goal in mind, and success will follow.

In a World Run by AI, The Best Data Wins

Like everyone else in martech land, I’ve been pondering the future of marketing in a world populated with AI. Most research I’ve seen agrees with this Hubspot report  that marketers’ top application for generative AI has been content creation (48%), followed closely by data analysis (45%) and learning how to things (45%). So it’s fairly clear that the immediate impact of AI will be to let marketers create vastly more copy, including real-time messages tailored to specific individuals. 

Extending this a bit, we can expect those real-time messages to be delivered within ever-more-finely tailored campaign flows (something else that AI can easily generate) or without formal campaign structures at all. These messages will be orchestrated and optimized across all channels, fulfilling the omnichannel vision that has hovered like a mirage on the industry horizon for decades. 

(Whether this results in more or fewer martech applications is a separate question. I tend to agree with this GP Bullhound study, which argues that “Any application introduced as an AI-enhanced alternative to an existing application or as a feature to a platform will likely become redundant when that incumbent platform implements the same AI features.”  This suggests that fewer specialist martech products will be needed, since truly new applications are relatively rare. Moreover, the productivity benefits of integrated suites are magnified when AI can easily orchestrate tasks within the suite, but not those on the outside. And, AI systems are inherently more adaptable than traditional software, which must be explicitly programmed for each new task. So extending existing applications becomes easier when AI enters the picture.)

Of course, what the humans reading this piece really care about is the role that they will play in this AI-managed universe. (Come to think of it, the AIs reading this may also care more than we know.) We’re frighteningly close to living the old joke about the factory of the future, where the one human employee's job is to feed the dog, and the dog's job is to keep the human away from the equipment. 

The conventional answer to that question is that humans will still be needed to provide the creative and emotional insight that AIs cannot deliver. (That’s what ChatGPT told me when I asked.)  Frankly, I don’t buy it: just as people who can fake sincerity, have it made, the AIs will quickly learn to mimic creativity and find which emotion-based messages work best.

Still, let’s be a bit optimistic and assume the marketing department of the future includes one human whose job is to feed the AI. Let’s even assume that human adds some creative and emotional value. The net result across the marketing industry as a whole will be that every company produces a wonderfully high and consistent level of marketing outputs. While that’s great in many ways, it also means that better marketing will no longer be a competitive differentiator. It’s a repeat of the situation in manufacturing since the 1970’s, when quality best practices were applied everywhere, so the differences between the best and worst products were often too small to matter. The winners in that world were companies who could use marketing to differentiate what in fact were commodity products. But when AI lets every company produce great marketing, then marketing itself is also a commodity.

So, how will companies compete in this new world? I’ve already argued it won’t be through emotional insight or creativity. I briefly thought that people might do better than machines at adapting to rapid change. The theory was that AI can only be trained on historical data so it will flounder when faced with unexpected events – which are increasingly common. But, let’s face it: humans also flounder in the face the unexpected.  It’s not at all clear they’ll be better than machines at predicting abrupt change, recognizing changed circumstances, collecting new evidence, and finding the new best actions. In fact, humans are heavily biased in favor of making decisions based on past experience, so I’d probably bet on the AI.

But all is not lost. I still see two ways for companies, and the humans who run them (for now), to distinguish themselves.

The first is customer experience. If you consider the true commodity industries, such as telecommunications, air travel, hotels, and financial services, what makes customers loyal to one or another provider is rarely the actual product or price. Rather, it’s the way they are treated. As a baseline, customers expect reasonable service, delivered pleasantly. But loyalty is really won or lost when there’s a problem or special request. This gives the company a chance to distinguish itself, either against an actual competitor or against a customer’s expectations of how they should be treated. 

Company policies and systems play a large role in what’s possible, but ultimately it’s the front-line employee whose training, attitudes, and choices make or break the experience. In the future, AI will surely play a larger role in managing these interactions. But, as with marketing, this will yield largely similar results because companies will be using similar AI systems. The differentiator will be the company’s people.

That's good to know, but customer experience is rarely under marketers’ direct control. This leaves one final straw for them to lean on: the data used to train their AIs.

Remember, AI programs themselves will be widely available. As with any other technology, the difference in results will depend on how they’re used, not any difference in the technology itself. Once AI systems are fully deployed, most decisions about things like content and program design will be made by the system, limiting the impact of user choice on the outcomes. But the one thing that will remain under users’ control is the data fed into the AI systems. It’s differences in that data that will drive differences in outcomes. In short: whoever has the best data, wins.

This is an area where marketers have a major role to play. They may not control the various internal and external systems who provide customer data. But they will have a large say in what those systems feed into the primary customer data store which, in turn, will feed the AI. Marketers who select the best data feeds will have a more effective AI and, thus, better final results. This will be true even though AI makes data collection easier: that will reduce the technical barriers to data gathering at all companies, but most barriers are actually organizational and budgetary. Those are company-specific decisions whose outcomes marketers can affect.

This may not be the cheeriest news you’ve heard today. Few marketers chose their career because they wanted to fight political battles with IT and customer success teams. But it does mean that many marketers can continue to play a major role in the success of their organizations, even as most of the traditional marketing tasks are taken over by AI. No doubt, the marketers who remain employed will sneak a few of their creative and emotional insights into AI prompts.  Maybe their inputs will even make a positive difference. But what will really matter is how good a job they do at feeding the AI with the best possible data.  That's what will empower it to deliver better results than the competition.

Remember: in a world run by AI, the best data wins.

Chat-Based Development Changes the Build vs Buy Equation

The size of most markets is governed by a combination of supply and demand. Typically one or the other is limited: while there may be a bottomless appetite for chocolate, there is only so much cocoa in the world; conversely, while there is a near-infinite supply of Internet content, there are only so many hours available to consume it. The marketing technology industry has been a rare exception with few constraints on either factor. The supply of new products has grown as software-as-a-service, cloud platforms, low-code development tools, and other technical changes reduce development cost to something almost anyone with a business idea can afford, and widely available funding reduces barriers still further. Meanwhile, the non-stop expansion in marketing channels and techniques has created an endless demand for new systems. Further accelerating demand, the spread of digital marketing to nearly all industries has powered development of industry-specific versions of many product types.

Despite the visibility of these factors, the uninterrupted growth of martech has been accompanied almost from the start by predictions it will soon stop. This based less on any specific analysis than a fundamental sense that what goes up must come down, which is generally a safe bet. There’s also an almost esthetic judgement that a market so large is just too unruly, and that the growing number of systems used by each marketing department must indicate substantial waste and lost control.

One common metric cited as evidence for excess martech is utilization rate: Gartner, the high priests of rational tech management, reported last year that martech utilitzation rates fell from 58% in 2020 to 42% in 2022 and ranted in a recent press release that “The willingness to let the majority of their martech stack sit idle signifies a fundamental resource disconnect for CMOs. It’s difficult to imagine them leaving the same millions of dollars on the table for agencies or in-house resources. This trade-off of technology over people will not help marketing leaders accelerate out of the challenges a recession will bring.” They were especially incensed that their data showed CMOs are increasing martech’s share of the marketing budget, comparing them to “gamblers looking to write-off their losses with the next bet.” (They probably meant “recoup”, not “write-off” their losses.)

This isn’t just a Gartner obsession. Reports from Integrate, Wildfire, and Ascend2 also cite low utilization rates as evidence of martech overspending.

It aint necessarily so.

For one thing, underutilization is common in all departments, not just marketing.  Nexthink found half of all SaaS licenses are unused. Zylo put the average company-wide utilization at 56% and Productiv put it at 45%. (These studies measure app usage, not feature usage. But you can safely bet that feature usage rates are similarly low through the organization.)

More fundamentally, there’s no reason to expect people to use all the features of the products they buy. What fraction of Excel or Powerpoint features do you use? What’s important is finding a system with the features you need; if it has other features you don’t need, that’s really okay so long as you’re not paying extra or finding they get in your way.  Software vendors routinely add features required by a subset of their users. Since that helps them serve more needs for more clients, it’s a benefit, not a problem.

The real problem isn’t presence of features you don’t need, but the absence of features you do. That’s what pushes companies to buy new systems to fill in the gaps. As mentioned earlier, the great and on-going growth of the martech industry is due in good part to new technologies and channels creating new needs which existing systems don’t fill. That said, it's true that some purchases are unnecessary: buyers don’t always realize that a system they own offers a capability they need. And, since vendors add new features all the time, a specialist system may become redundant if the same features are added to a company’s primary system.

In both of those situations, avoiding unnecessary expense depends on marketers keeping themselves informed about what their current systems can do. This is certainly a problem: thanks to the miracle of SaaS, it’s often easier to buy a new system than the fully research the features of systems already in place. (Installing and integrating the new system will probably be harder, but that comes later.) So we do see reports of marketers trying to prune unnecessary systems from their stacks: for example, the previously-cited Integrate report found that 26% of marketers expected to shrink their stacks. Similarly, the CMO Council found 25% were planning to cut martech spend and Nielsen said 24% were planning martech reductions. (Before you sell all your martech stock, you should also know that each report found even more marketers were planning to increase their martech budgets: 32% for Integrate, 36% for CMO Council, and 56% for Nielsen.)

Let’s assume, if only for argument’s sake, that marketers are reasonably diligent about buying only products that close true gaps. New gaps will continue to appear so long as innovation continues, and there’s no reason to expect innovation will stop. So can we expect the growth in martech products will also continue indefinitely?

Until recently I would have said yes (unless budgets are severely crimped by recession). But the latest round of AI-based tools has me reconsidering. 

Specifically, I wonder whether marketers will close gaps by building their own applications with AI instead of buying applications from someone else. If so, industry expansion could halt.

Marketers have been using no-code technologies to build their own applications for some time. Some of these may have depressed demand for new martech products but I don’t think the impact has been substantial. That’s because no-code tools are usually constrained in some way: they’re an interface on top of an existing application (drag-and-drop journey builders), a personal productivity tool (Excel), or limited to a single function (Zapier for workflow automation). Building a complete application with such limited tools is either impossible or not worth the trouble.

The latest AI systems change this. Chat-based interfaces let users develop an application by describing what they want a system to do. This enables the resulting system to perform a much broader set of tasks than a drag-and-drop no-code interface. That said, the actual capabilities depend on what the model is trained to do. Today, it still takes considerable technical knowledge to include the right technical details in the instructions and to refine the result. But the AIs will quickly get better at working out those details for themselves, drawing on larger and more sophisticated information about how things should be done. Microsoft’s latest description of copilots and plug-ins points in this direction: “customers can use conversational language to create dataflows and data pipelines, generate code and entire functions, build machine learning models or visualize results.”

What’s important is that the conversational interface will drive a system that automatically employs professional-grade practices to ensure the resulting application is properly engineered, tested, deployed, and documented. In effect, it pairs the business user with a really smart developer who will properly execute what the user describes, let the user examine the results, and tweak the product until it meets her goals. Human developers who can do this are rare and expensive.  AI-based developers who can do this should soon be common and almost free.

This change overcomes the fundamental limitation of most user-built apps: they can only be deployed and maintained by the person who built them and are almost guaranteed to violate quality, security and privacy standards. This issue – let’s call it governance – has almost entirely blocked deployment of user-built systems as enterprise applications. Chat-built systems remove that barrier while fundamentally altering the economics of system development.  More concretely: building becomes cheaper so buying becomes less desirable.  This could significantly reduce the market for purchased software.

Anyone who has ever been involved in an enterprise development project will immediately recognize the flaw in this argument: there’s never just one user and most development time is actually spent getting the multiple stakeholders to agree on what the system should do. Agile methodologies mitigate these issues but don’t entirely eliminate them. 

Whether chat-driven development can overcome this barrier isn’t clear.  It will certainly speed some things up, which might enable teams to build and compare alternative versions when trying to reach a decision. But it might also enable independent users to create their own versions of an application, which would probably lead to even stiffer resistance to adopting someone else’s approach. 

One definite benefit should be that chat-based applications will learn to explain how they function in terms that humans can understand. Responsible tech managers will insist on this before they deploy systems those applications create.

In any event, I do believe that chat-built systems will make home-built software a viable alternative to packaged systems in a growing number of situations. This will especially apply to systems that fill small, specialized gaps created as new marketing technologies develop. Since filling these gaps has been a major factors behind the continuous growth of martech, industry growth may slow as a result.

Incidentally, we need a name for chat-based development. I’ll nominate “vo-code”, as shorthand for voice-based coding, since it fits in nicely with pro-code, low-code, and no-code. I could be talked into “robo-code” for the same reason.
