Robots being able to perform any task a human can do, physically, doesn't seem that far off. They would be powered by AI of course.

The question is: do we still have to work? If not, who will take all the wealth?

We thought the washing machine would have giving us so much free time, because it used to take a full day a week. Instead, we only got more frantic it seems and started putting in more labor. But what will happen when that labor is worthless?

In a dystopian world, the elite may be better off just killing the lower, middle and even the higher classes. Keep just enough people to have an interesting gene pool around. Because even in the space mines there will be no need for human labor anymore.

Even with more fabric, doing laundry takes a fraction of time it used it. We replaced most of that time with something else.

For the present, human bodies are far more capable than robotic ones.

Appliances like the washing machine literally killed the market for "hired help" in the anglosphere. In-house servants used to be relatively common among the middle and upper classes; with the aid of electrical appliances, the time/money costs of doing the laundry, dishes, and so forth went down so far that only the very rich care to hire servants as a mark of status.
