We're now reaching the point where people have gone their whole college education on AI, and I've noticed a huge rise in the number of engineers that struggle to write basic stuff by hand. I had someone tell me they forgot how to append to a list in their chosen language, and couldn't define a simple tree data structure with correct syntax. This has made me very cautious about maintaining my fluency in programming, and I'll usually turn off AI tools for a good chunk of the day just to make sure I don't get too rusty.
