This feels like wishful thinking. Any automated system (cars, LLMs, etc) only need to be better than a human doing that job. Your example, for, um, example, ignores that self-driving trucks don't need to take sleep breaks, or bathroom breaks, or spend time with their families, etc.
Using the assumption that this is the bottom of the curve for this LLM technology and that we still have a lot of expansion in the tech coming in a relatively short amount of time, then I would guess that any job that makes art that is "work for hire" will cease to exist, and I imagine programming is going to take a pretty big hit in available jobs. I don't think you'll be able to get rid of human programmers altogether, but you'll need way fewer of them.
