I think this is the result of a c-suite that has never actually done the work of the businesses they're running. The MBAificiation of management. Of course they constantly do brain-dead shit, they literally don't have a clue how anything actually works in "their" own business.

They've been vibe-driving businesses long before we've started vibe-coding software.

I was trying to think of a way to word this exact argument. I think it’s especially easy when your business technology is not your primary means of revenue generation. Having these execs understand how things work is significantly less critical in these scenarios, so it becomes much easier to hire for alternative characteristics (golf game, pedigree, gender, whatever).
