Why not?

Surgeons already perform remote surgery, so physical dexterity isn't the issue.

What do you think the moat is? Computer vision? Surgical technique? Surgical knowledge? Medical knowledge?

Maybe surgeons will be smart enough not to allow AI to be trained to do what they do, but it seems that training data is the only real barrier.

Why are we believing in marketing lies? For instance, crypto is useful (in a narrow context) even if it's 99.99% scams, and has positively impacted at least some people (the unbanked), even if it fell short of replacing the world's banking system. It's good tech.

Similarly with LLMs, it's good tech, but I do not believe for a single second that these things will ever replace anyone who is remotely skilled. People will be augmented by them. They won't be fully replaced. Well, I hope not anyway.

Surgery is a regulated field with high barriers to entry. Even if surgeons did not get replaced, displaced humans in other fields would not find employment in surgery.

I don't think so but it will not stop folks from trying. The panacea of AI is AGI which basically, in theory, will replace any human/thing.
