Yes, this poses political problems and it will have to be hashed out politically. Again, the problems with these are political not necessarily technological. And they are also tractable. There are many many possible ways this can play out and we should be careful which we choose. I just don't think the conclusion is foregone. There have been people's jobs displaced in the past. And things settled eventually. I won't argue they settled for "better" because many people are unhappy about many things, but I will say... the world is amazing.

At the risk of sounding like a longtermist, I think that when all is done, the result will be a net positive one, but it WILL cause strife for many people - probably me included. But I refuse to keep my childern's future hostage because I might have to reskill.

If you are speaking about the world, hundreds of millions in the next 5 years is probably closer to reality in my opinion. And from your question I think that you already know the answer.
