I agree. But, we will need a lot fewer of them. My small company called our lawyer a lot more before the advent of AI. Mostly to clarify a few things or review simpler contracts. Now, for simple things, we do not call them at all.
(1) Rich people will use human expertise and "the rest of us" will use AI models to get by. This could happen in law, but also in medicine (in particular in societies that - like in the US - do not have universal healthcare).
(2) A positive effect in both domains may be that access to knowledge will be broader and cheaper.
I hope I will be wrong about (1) - I would not like to live in such a two-class society.
