I'm not worried that LLMs, as they currently and foreseeably (i.e. 18 months) are, will be a good substitute for high quality developers like me.

But oh boy have I seen a lot of mediocre coders get away with mediocrity for a long time — there's a big risk that employers won't care about the quality, just the price, for long enough that the developments in AI are no longer foreseeable.
