Oh I love made up analogies (which are not inherently arguments, look up formal logic) with made up statistics. Thanks to your sheer perspicacity I'm now completely sure that after having honed my craft and suffered through intensive formal education for years on end I'll just "retrain" or "move on to other (which ones exactly remains a mystery) fields".
Surely, even the 750 people from your imagination all successfully retrained to become professionals in completely novel fields of work in their 30s-40s-50s. None of them drank themselves to death out of the feeling of utter uselessness; none of them lost their families, which they couldn't support anymore; none of them turned to crime, thus ruining communities, lives of other people; none of them committed suicide after becoming homeless. If you love car analogies so much, maybe take a look at the fine city of Detroit and its recent history, what an absolute fairy tale.

All the robotics that have been implemented throughout a very narrow range of industries and locales have been heavily regulated, which prevented a lot of manufacturing facilities going all robot.
"But the big daddy from OpenAI/Microsoft told us that we will all receive 13k as basic income, I'll buy all the funkopop superhero toys on Earth with that money, while not doing anything at all!"

They sure can't just exploit their property rights on this technology, or just get rid of those pesky mediocre humans, as whatever their hearts desire could be fulfilled by one very advanced AI model and a bunch of specialised robots, instead of thousands of hard-working interns, seasoned professionals and laborious technicians.

Humankind has always been about suffering through life. Our entire knowledge systems, works of art and world cultures are built by and around people who sacrificed their comfort, well-being and time on this planet to discover something, achieve a goal, become a source of wisdom, knowledge and mastery. No matter how unique their field of work is. Automation of all work that has a sliver of creativity element to it culls the entire human population to the left of 2nd standard deviation above the mean, leaving only a very limited number of geniuses (who got to be born, raised an educated in the best combination of circumstances) still necessary to advance knowledge and oversee the work of whatever AI system that will end up performing the best.
Who will the future children look up to? Some abstract mathematical concept known as a transformer machine learning model?
That is if there will be any children in the future anyway...
