True, and we've been here before. The industrial revolution got rid of the need for most labor, which at the time was overwhelmingly agricultural and textile. We came out the other side OK.
But there was a lot of pain. Living conditions got worse and stayed worse for entire lifetimes before they got better, and they didn't get better because the people who won decided to deal in the people who lost, they got better because the world went to war and incinerated most of its capital, literally and metaphorically, and the regrowth happened under conditions of scarce labor rather than abundant labor, allowing the people on the bottom to strike a decent deal the second time around.
That, uhh, won't happen the same way again. Now we have robots and nukes. But it's true that without the benefit of hindsight I'd have had an apocalyptic view going into the last kerfuffle, I'd have been wrong, and it would have been due to a failure of imagination. Let's all hope that I am wrong again, but the mechanism will again have to be a failure of imagination, and it takes a lot of optimism to fit my hope squarely inside my blind spot.

No, living conditions did not get worse. Yes, livings conditions were pretty bad during the early industrial revolution. But they hadn't exactly been rosy before.

Which war are you talking about? There's been more than one, you know. And the decades after the second world war were probably the nadir for humanity: we never had as many dirt poor people as then and will hopefully never have as many. Remember, that's the time when there were genuine fears of global starvation. Things have been looking up a lot since perhaps around the 1980s and even more so in the following decades. Mostly thanks to PR China and India and South East Asia graduating from dirt poor to merely poor or even middle class.
You also seem confused. You seem to say that a relative capital scarcity is good for labour ('incinerated most of its capital') but also that relative labour scarcity is good for labour? Which way is it?
