> All else being equal, you want to produce more with less labor and other inputs

Is that actually true? Maybe I'm being dense right now but that's not completely apparent to me.

More abundance per person does seem generally better (albeit there's eventually diminishing marginal utility), but that's not the same thing as society as a whole producing more with less labor.

Maybe "all else being equal" is the operative condition here, like assuming that the economy would be able to absorb newly freed labor into new economic activity?

You can also optimize some good things out of existence in this manner, and it's still not clear that robots are going to be able to swoop in and save that kind of newly uneconomical activity, at least within my lifetime.

Yes, it is the same thing. There's no difference.
