I don't think AI is going to eliminate all jobs, in fact IMO there will be LOTS of jobs completing tasks AI identifies and also managing the scope AI manipulates, assesses, is involved with business units.
Computers did, have, and will continue to displace humans in some jobs, and create other jobs as well. Computers were supposed to reduce/eliminate "paperwork and admin tasks" and make jobs easier. Ask a 15-20yr+ experienced nurse of any discipline of medicine if automation/computerization has freed up time for them to spend on patient care.
The US is currently as computerized and robotized as it's ever been and unemployment hovers just over 4%. It's been a long while since I took an Econ. class, but IIRC, ~4% unemployment is considered "Full Employment" in the US.
Yes, there's very assuredly big fast changes coming. I believe the adaptable and motivated folks will continue to have fulfilling jobs they want to do and will be paid enough for the standard of living they realistically aspire to.
