My parents had a weird green card and paperwork issue that was becoming a big problem. Everyone in their social circle recommended an immigration type lawyer. Everyone.

My dad was confident he could figure it out based on his perplexity Pro account. He attacked the problem from several angles and used it for help with what to do, how to do it, what to ask for when visiting offices, how to press them to move forward, and tons of other things.

Got the problem resolved.

So it definitely can reduce hiring lawyers even.

Lawyership in the sense of the profession may survive and adapt. Individual lawyers, not so much. I strongly doubt the new equilibrium (if we ever reach one) will need so many lawyers.

Same logic for software developers.
