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.

I'm not ignoring that, but you're ignoring that these systems have their own associated costs. A self driving truck might not need bathroom breaks, but it does need regular maintenance which given the increased complexity of such a system is going to be significantly more expensive than a normal truck and require more skilled labor to properly maintain. That's why I said it's more expensive, but large companies can make it up in volume. The extra expense only makes sense if you can take advantage of the E.G. increased transport capacity provided.

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.

You're assuming that LLMs can ever be made accurate. I think you might be able to make them somewhat more accurate, but you'll never be able to trust their output implicitly. You will always need someone reviewing and fixing what they produce. For something entirely subjective like art that's probably acceptable, but not for anything that requires any amount of accuracy.

As a programmer I am absolutely not worried in the slightest that LLMs are coming for my job. I've seen LLM produced programs, they're an absolute trash fire, most of them won't even compile let alone produce correct output. LLMs might be coming for really really bad programmers jobs, but anyone with even a shred of talent has nothing to worry about.

There's a famous saying out there about programming that goes:

You can write a program that's so simple there's obviously no problems, or a program that's so complicated there's no obvious problems.

LLMs are very much an exercise in the later not the former. I'm sure there will be a bunch of jobs soon for programmers to check and fix LLM generated code, but you couldn't pay me to do that job. That's going to be absolutely miserable work and way harder than just writing the code yourself in the first place. Ultimately companies are going to figure out it's cheaper to just skip the LLM in the first place and then the whole thing will be dead. One things for sure though, you won't need fewer programmers, you'll need more of them.
