Resource consumption often goes up. It's a time vs energy tradeoff and it's not free.

Your question is a variant of what do we do with all those humans now that they don't have to walk miles to the well every day because we invented aqueducts? The point is that they didn't want to walk to the well but they had to (and in some places they still have to) and very few people want to work, even now and even us, but they have to.

We will see what happens this time when we won't have to walk to that well.
