It's good that we'd be able to increase the amount of goods and services produced and reduce prices. For example, a lot of people would benefit from access to cheap, reliable heart surgery within a few days of learning they needed it. It would be good if the exponential growth that has elevated our wellbeing for the last millenia wasn't tethered to exponential population growth that would be disastrous if we even expected it to continue.

It would be bad to remove demand for humans from the economy, of course. Humans have inherent moral value, and so it's good that our current system gives them economic value as well. But there's more than one way to achieve that end, and the massive quantity on the good side of the scale suggests it may be worth investigating the others instead of opposing the advancement outright.

If all goes well, imagine a world in which you work because you want to not because you have to.

It's good for capital holders. It does imply a further shift in the distribution of wealth though with all the attendant implications thereof.

I question the premise that humanoid robots are "around the corner". I suspect this will turn out more like self-driving cars which are still a very slow burn.
