>people are underestimating how draining is operating and maintaining software

Yep. Many SaaS have an edge because they factorize the struggle of many customers, if a SaaS has 1000 customers, each customer vibing their way into a home-built solution will require dedicated efforts at maintaining it. Even with AI, those efforts aren't negligible.

Many companies don't even operate any IT infrastructure, cloud or otherwise, themselves, beyond office connectivity, AI replacing SaaS will require someone in charge of that at the very least.
