There is a point in there, long-range analysis and debugging without AI is much harder, AI spots lots of non-obvious stuff very fast. If we consider "spotting non-obvious flaws" a skill, this will atrophy as beginners will learn to use AI to scan code for flaws,it is effective but doesn't teach anything, reading long blocks of code and mentally simulating it is a incredibly valuable skill and it will find stuff AI misses(something that is too complex, e.g. nested/recursive control flow,async and co-routines/threads interacting,etc), AI goes for obvious stuff first and has to be manually pointed to "identify flaws, focusing on X".
