I mean, think about the dishwasher, the washing machine, and the vacuum cleaner. Did they bring significant human productivity gains?
Nope. We just bought more dishes, more clothes, and bigger houses. And then we went to work to buy more highly-automated versions of them, and to purchase even more dishes, clothes, and house. The same type of work is being done, in the amount necessary for one household (and there are fewer people and more things and floor space in the household). Is the shifted labor more productive? Probably not, as it took women out of the home and collapsed the birth rate, and human production is the most-useful production.
