Then disagree with the premise. Is it wrong? Why is it ridiculous? Are the adavances in robotics and ML that we are currently experiencing going to hit a wall soon?
It's not that advancements are going to hit a wall. It's absurd to assume human demand for consumption is finite. There will always be human desires that cannot be satiated by machines.
Even if that's true, it doesn't say anything about ratios. Say 90% of our needs are met by machines, 10% is not, we still have a huge problem in terms of labor/capital value mismatch.
