It's not really that different from what has already happened - we need fewer workers in the economy due to technological advancements, and jobs that were common 50 or 100 years ago don't exist any more or are much more rare.
It's a problem of distribution. Capitalists used to depend on buying capital, which gave workers some share of their money by default. In countries where capitalism worked better, the proletariat successfully organized, giving workers a position of power vis-a-vis the capitalists and improved their conditions. Hell, in some countries the situation even got bearable for a little while, helped along by the exploitation of foreign work forces.
As the capitalists replace more and more workers by machines, money stops flowing, and the position of the proletariat is relatively weakened.
In theory, it's not a difficult problem at all. In democracies, the proletariat can simply vote to tax the rich, making money flow downwards and ensuring their rights and welfare in the same way as when they had to sell their labour.
One could also go full on communist, remove private incentives in form of capital gains, and collectivise the means of production. This would require massive political organisation and a lot of goodwill from humans put in power, for which mankind has a terrible track record.
Taxing the means of production and the capitalists, however, is not particularly difficult. It's been done with great success on many occasions.
The problem is that the capitalists have a lot of influence, and they're not interested in letting go of their money bag. Disproving the point that they got wealthy by having any form of heightened intelligence, they're too dumb to realize that if they leave behind nothing but a destroyed hellscape for the rest of humanity, their lives aren't going to be very pleasant either. Humans tend to be happier in more egalitarian societies, yet the capitalists are hell bent on gathering more for themselves, buying media channels and politicians in the pursuit of effectively just making everyone else poorer relative to themselves.
So we're fucked, not because of the distributive effect of technological advancements per se, but because we're collectively incapable of successfully organising for continued wealth distribution. And all the technologies used to replace workers comes at a high environmental cost, making our time horizon to find solutions increasingly limited.
