I dunno I find it almost more important than ever to have deep domain experience. You need to be able to scan output and spot any problems/improvements instantly. If I am just auditing AI output around an area I don’t have mastery of I am basically useless.

A stack is still not a domain. You could have domain expertise in building highly scaled distributed systems and still not call yourself a ____ programmer. The point is that your value lies more in knowing how to build for performance, consistency, reliability at scale and not in knowing where the semicolon goes.
