Someone was saying that even if using machines becomes cheaper than using humans, capitalist will still use humans because
"automation constitutes constant capital and human labour is variable capital
The Tendency for the Rate of Profit to Fall disproves that fact"
What do those mean?
We don’t have general purpose AI yet, but I don’t think that’s a prerequisite for automating many jobs out of existence. Humans will still be needed to solve really complex problems for the foreseeable future, but the number of humans that need to work will be greatly reduced. A great example we can already see today are automated ports and factories in China where there’s a just handful people overseeing them.
