They're not coming for all jobs. There are many jobs that exist today that could be replaced by automation but haven't been because people will pay a premium for it to be done by a human. There are a lot of artisan products out there which are technically inferior to manufactured goods but people still buy them. Separately, there are many jobs which are entirely about physical and social engagement with a flesh and blood human being, sex work being the most obvious, but live performances (how has Broadway survived in an era of mass adoption of film and television), and personal care work like home health aids, nannies, and doulas are all at least partially about providing an emotional connection on top of their actual physical labor.
And there's also a question of things that can literally only be done by human beings, because by definition they can only be done by human beings. I imagine in the future, many people will be paid full time to be part of scientific studies that can't easily be done today, such as extended, large cohort diet and exercise studies of people in metabolic chambers.
