I've noticed this too. Because people are generating work so quickly , and maybe not understanding it entirely, then they hit a bug, pivot, and pretend it was the plan the whole time. Or drop something they were very excited about 3 days ago and never speak of it again.
There is a lot more hustling and bravado.
It feels like people don't value knowledge as they used to.
It's really hard to avoid mistakes when everyone is subtly covering them up. It feels like a lack of care and I find it demotivating.
I think because engineers are afraid for their job, they are under more pressure to talk a big game. Also under more pressure to deliver short term visible results. Bad combo.
