I think deskilling is an underrated concern. Programming among the competent is a mind-body experience and a matter of motor memory and habits of mind, and LLMs make you extraordinarily lazy.

No matter how 'senior' you are, when you lose touch with the code, you will, slowly, lose the ability to audit what LLMs spit out, while the world moves on. You got the ability to do that by banging your head against code the hard, "pre-AI" way, perhaps for decades, and if you don't do the reps, the muscle will atrophy. People who think this doesn't matter anymore, and you can just forget the code and "embrace exponentials" or whatever, are smoking the good crack; it _is_ about the code, which is exactly why LLMs' ability to write it is the object of such close examination and contestation.

Folks who realise this will show to advantage in the longer run. I don't mean that one shouldn't use LLMs as an accelerant -- that ship has sailed, I think. However, there is a really good case to be made for writing a lot by hand.
