As someone who believes AI will completely eliminate humans I wish I was could only be worried about job security.

But to answer your question, AI will ultimately eliminate every job in the sense that if you believe AI will eventually be able do any task, and do it for cheaper than a human labourer, then there would be no reason for you to ever pay a human labourer.

The best analogy here is probably how the industrial revolution made the horse redundant. It's not that horses can't be used for physically demanding work anymore, it's simply that it's cheaper in practically every imaginable case to use a machine so horses are no longer used.

Of course, machines didn't replace the use of horses in all industries over night and we should expect the same will happen with AI. I'll assume this is what you're asking.

It seems rather obviously to me that knowledge workers will be the easiest to replace with AI – especially knowledge workers who work purely digitally. The hardest work to replace will likely be physical labour since robotics is still very far from biological sophistication required to be competent at many physical jobs. And even when it starts to become competent it's going to take a while to build the robots to replace labourers and do so at a competitive cost.
