It's not about jobs, it's about income...
Excuse the tangent, but when people say they're worried about robots/ computers/ immigrants "taking their jobs", what they actually mean is that they can see their income stream disappearing.
Under the current neo-liberal capitalistic setup, those who run the businesses are on a race to the bottom, driving down their business costs by getting the cheapest labour to maximise their profits which are then distributed to their share holders, meanwhile those who have lost their income have to rely on State Benefits (if there are any) or scratch out a living on a minimum wage job whilst a few at the top of the pile get richer and richer.
Douglas Adams summed this up nicely with the Magarathean Planet Builders who catered for the extremely rich "But this was perfectly natural and nothing to be ashamed of, because no one was really poor - at least no one worth speaking of." Of course it ended up with so much wealth being concentrated in so few hands that the economy collapsed...
Naturally some (TW comes to mind) would argue that people are "better off" because goods become cheaper, but they don't become cheap enough to counterbalance the loss of income and, meanwhile, the wealth still flows upwards and does not "trickle down" to the people who will actually spend it, rather than salting it away in lucrative (for them) tax avoidance schemes.
So arguing about "professional classes hollowing themselves out" or their jobs being taken over by AIs is a bit of a red herring, what's important is whether money can be made to flow back down from the top such that the economy keeps running. If that doesn't happen, the rest of the argument is merely academic.
