Unless you believe in souls or some other form of dualism, then clearly machines will eventually be able to do anything we can do.

But we're far from that point now. Anything machines can currently do is, pretty much by definition, drudgery. I'd be happy to reevaluate that statement if and when this changes.

I have no idea what the ultimate answer to that question would be. Lots of SF authors have tried to address it, coming up with answers varying from humans always having something they can do better, to humans existing to have fun, to humans having no point at all and therefore get wiped out by the machines.
