i think these jobs do exist, yes, and probably will support some number of humans. but in the traditional form, less than people think - ai therapists are actually pretty popular, and regardless i think an economy has to be more than just people servicing each other. you need linkages, cybernetic feedback loops running into the ai-industrial economy. though my optimistic future scenario does have relational-ish jobs done by humans for ais, so maybe it does end up mostly this way for us.
