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 aided by LLMs. In a similar way, I also expect smaller qualified teams (3 to 5) to leverage LLMs to become more relevant competitors of medium to large SaaS players. By 2029, we'll have more, but smaller SaaS companies.
