How do you propose those "BS artists" feed their families in an alternate reality tech industry where only the roles that add value are deemed worthy of food and shelter coupons?

A good first step would be let them keep their jobs, but strip them of any authority. This already happens at some companies - the architects provide guidance which dev teams are not required to follow.

I think it's absolutely insane that we live in a world where many people with an "architect" title don't write code, and sometimes have never written code in their life! That would be like a world full of chess coaches who don't play chess! They just read BS articles like "Skewers are the new forks" or whatever.
