Who is going to chop the wood for the cooking fire?
Who is going to churn the butter?
What galley slaves will row the cargo ships?
Who is going to drive the oxen ploughing the fields?
Reading the article reveals that the first thing in it is a woman who was annoyed by women having to clean the home, and who invented a self-cleaning home. That was in the 1970s. We're long past being able to have self-cleaning toilets if we wanted that. And pre-fab homes. And and and.
You can retreat into 'God of the gaps' of ever-shrinking necessary work, but that's usually a last ditch argument by people who have nothing stronger to argue with. Goodness forbid that your position be reduced to "toilets should have to be cleaned by a person, and it should be organised by money, so done by someone poor" as that would be strawman bad.
Yes self-cleaning toilets would take iron ore mining and steel manufacturing and so on, but factory work has been more automatable decade by decade, and it won't be a thousand years of current rates of change before basically everything is automatable.
It's useless trying to predict what human society would be like in 1000 years. I've read enough scifi to notice that none of the authors even get 20 years into the future right, not even close.
