UBI (giving people money to buy things) is a good step, but it's not enough in the current economic system unless we also start systematically lowering costs and eventually making items free. Just giving people money doesn't do away with the need for money (and, in fact, just ends up transitioning ones reliance on a job toward a reliance on a government subsidy instead). Even if universal prices don't rise to mirror any implemented UBI (which I doubt), limiting what people can have by the amount of money they have will always result in people wanting more money to have more things.

In order to completely do away with the pursuit of the accumulation of money, there'd have to be no reason to have money. Ergo, everything would be free or available as needed. In order for that to happen, we need a post-scarcity society where there are enough resources for everyone to have whatever they want and can do away with our money-based filtering system that decides who gets what.

AI is a powerful tool to get to such a society by automating our jobs away and producing goods at a lower cost compared to human labor, which allows companies to race to the bottom on costs.

AI is not another mouth to feed.
