There's only one universal lesson that I've learned over my 25+ year career so far and it's that software engineering types are fragile creatures whose egos must be tended to. Delicately.

This is becoming increasingly true as the years pass and the number of times I've had to drop whole mature architectures and reimplement something worse because some engineer's feefees got hurt can no longer be counted on my fingers & toes.

This is 180 degrees from teams I have been on some years ago - everyone took pride in being thick skinned and detaching their ego from PR reviews. Seems to be a generational thing
