Fair enough. The rate of technological advancement keeps increasing.

So far, what you’re describing never occurred. It even has a name in economics: The Lump of Labour fallacy.

However, as changes become more and more rapid, it might be the case that labour will not be able to adjust as quickly.

In any case, I’m not particularly worried because I believe that even if it all goes to shit, it will be short term pain for long term gain. Humanity has dealt with so much worse over the ages and we’ve always managed to prevail. If a revolution of some kind becomes necessary to guarantee UBI or something like that, then be it.

In any case, long term we will be in a better society. And that’s what I ultimately care about (and not having to work too).
