Most people in this econonic system have to work to earn a wage in order to pay for their living. That combined with large swathes of people being made redundant and not able to earn said wage is gonna be a problem.
Came here to say this. Nobody is saying "I want to work forever", we're saying "can we not replace work while our entire global civilization is predicated on working to survive?"
JFC, if AI replaces work wholesale right now billions of people will die before society is reshaped accordingly. More people need to think of immediate systemic impacts instead of the high-fantasy post-work future the AI folk are selling.
With all due respect, if the economic system no longer serves us, then we deserve one that does.
