Do some people really believe that SaaS margins are dropping because the public at large has discovered that to save 20$/month on some app they can instead vibe code their own and use that instead? My current guess about the future is that the age of SaaS is coming stronger than ever. I expect many vibe coders to come up with half-assed prototypes that will be copiously replicated and improved by more qualified devs…
If you've already figured out what features are actually needed and which workflows work best, somebody can use AI to replicate those. This is the part of programming that AI is best at and accelerates most. The hard part, coming up with ideas, is far harder to copyright.
