All paradigm shifts and regime changes happen because of a coalition of people that have nothing to gain and everything to lose by the current system.
But I think we should decouple mediocrity from laziness. I haven't seen any team invest in the mentorship required to develop juniors in years, for example.
The incentives for developing juniors have become misaligned as the expected stay in a company dwindled from decades to years to maybe year.
It would make sense to develop juniors if most of their comp was a four year vest but that doesn't happen until later. And in your first year or two you're usually a net negative... This is even more true with AI.
