I doubt it, and from what I hear it's the opposite. I sat with a potential client just today that had a sort of working mess of vibe coded stuff to handle parts of his business (one man show). He was now looking for a proper solution to replace because it took too much time to maintain, it was unstable, etc. He wanted something that just works that he can rely on.

I think a lot of SaaS tools have a great future. But they will require less engineers to build.
