That's still very much true, but at least in the case of Linux the cost is getting lower and lower all the time. The time investment for many has reached about the same as the cost needed for Windows and as a result we see more and more people using linux. At this point it's a perfectly viable gaming platform!

Maybe one day LLMs will eventually make good code at a low cost, and that will allow non-programmers to write programs with few problems but the cost will never be zero, and I think we're a long long way from making human programers obsolete.

All of the intelligence that LLMs mimic came directly from the work of human minds which got fed into them, but what LLMs output is a lossy conversion filled with error and hallucination.

My guess is that the LLMs producing code will improve for a short time, but as they start to slurp up more and more of their own slop they'll start performing worse.
