You sound like people explaining that chess is something a computer can never beat a human at because of some mystical sense we are supposed to have (it was quite some time ago). They quickly changed their tune to "chess isn't very hard anyways" when Kasparow got schwacked by Deep Blue. Back then peiple hated on automation.

We humans will never be better than our training data either, and we forget and get old and die.

I'm more interested in figuring out what we should do with all the computational power and potential labour. The robot was just an example, a metaphor, for AI doing boring work. It will be able to write sonnets and generate world class movies one day, what shall we humans do then? Be happy? Do art?
