I believe paper publishing scientists will be amongst the last to be replaced, albeit the lab technicians and assistants doing less innovative work will be far sooner. By the time AI can publish scientific papers to the point of replacing scientists themselves, this is it, we already reached the singularity.

Problem is, this type of innovative work likely requires minimum >120 IQ, which is 1 in 11 people. If you don't reach that cutoff, the remaining options will mostly be traditional manual jobs requiring <100 IQ, or those that benefit from physical human interaction, such as therapists and prostitutes. Basically the middle class, middle cognitive demand jobs for people between 100 and 120 IQ will be eradicated.

If it is difficult to monetize a career in entertainment now, it will be an order or two of magnitude harder in the future, due to competition with AI generators and performers.

Even assuming you have the AI to control robots, the raw materials and fuel to power them cost a lot of resources, and manual laborers are amongst the cheapest, so as long as the robots remain costing more than 4 or 5 years worth of wages, which adds up to 150k to 300k USD in America, plumbers, electricians, and housekeepers will keep their jobs.

We are heading towards a society in the 2030s being stratified as such, in order of wealth:

1. Capitalists (~1%)
2. Entertainers and Performers (~0.05%)
3. Innovation STEM jobs (~5%)
4. Management and administration (~5%)
5. Physical interaction jobs (~5%)
6. Manual labor jobs (~30%)
7. UBI majority (53.95%)
