I wonder how much of this universal lesson will be rehashed to fit the aftermath of what's currently going on with vibe coding etc.

I think it's pretty likely that in, let's just go for the round number and say 80% of cases, everyone will conclude that just existing well used frameworks / code generator templates where everything's understood and most of the hot paths are well tested is pretty fast to build with (and more importantly, maintain and operate) and was really all we needed for most useful business software.
