This is the new normal now that computer science based SWEs are being replaced with "LLM whisperers". Being 10 times more productive with AI necessarily means you're going to have 1/10th of the understanding of the code you're producing. It physically couldn't be any other way.

The scary thing is that the system moves in a direction such that it seems that it doesn't really matter. People on an individual level care but due to the strange economic conditions, LLM use is still rampant because experienced people can get some benefit from it in the short-term even if that means the long-term degradation of our collective expertise and thus a net negative. It's blindingly obvious but just like climate change, people can't help on an individual level to take the immediate reward.
