Jevons Paradox likely applies here. There could be an initial reduction in jobs, but longer term humans using AI will reduce the cost (increase the efficiency) of those jobs which will increase demand more than merely satisfy it.

Basically any job that uses a word processor, spreadsheet, drawing tool, etc will all become more efficient and if Jevons Paradox applies, demand for those things will increase beyond the reduction due to efficiency gains.

I can imagine that for many fields it will be cheaper to have humans use AI (in the near term) rather than try to make fully automated systems that require no/little supervision.
