The variation in individual developer throughput was as much as 20x pre-AI. 10% is basically nothing. You’d be better off firing your worst performer and replacing them with someone good (or great).

Good luck getting those devs. Between the fallout of covid and AI in education, there is likely half an upcoming generation poorly educated and comparatively less qualified.

Right now the market favors employers, but I think when the sobriety sets in this will rapidly change. Senior devs are gonna get more expensive. Companies should massively invest in education programs.
