A friend of mine recently came back from a conference session on “vibe coding” with the kind of energy you only get when something fundamental has shifted. They are smart, tech-enabled, and fully comfortable around digital tools, but they are not a programmer. After a brief introduction, they sat down and built several applications. Not toys. Not abstract demos. Useful applications that solved real problems in both their daily life and their professional work. They even shared those applications with colleagues. And, as is often the case with these new tools, the apps were not only functional. They were polished, themed, and appealing to use.
That story is easy to file under amazement. It is harder, and more important, to recognize it as a signal. The computing world is going through a fundamental shift that changes the locus of invention. Before – and almost every programmer has had this experience, I suspect – non-developers would come up to you and tell you an idea, then try to get you to help them make it happen. Now they can do a lot of the hard work themselves!
The signal, though, is not that everyone should now go build production systems from a prompt window and hope for the best. The signal is that the distance between understanding a problem and expressing a solution in software has collapsed. The people closest to the work can now participate in shaping the tools they need in a much more direct way. That is the breakthrough. And in the financial services sector, where structure, security, explainability, and accountability are non-negotiable, the way to turn that breakthrough into something durable is not vibe coding. It is spec-driven development.
If we want a world where everyone can get to what they need to do, their way, even inside the highly governed world of banking, wealth management, lending, life insurance, reinsurance, property and casualty insurance, and credit card processing, then spec-driven development should become the new citizen development model.
