It is very useful for coding because that is one of the few places where unoriginal repetitive solutions are often desirable. But even with coding you have to know what to tell the LLM to do and you have to be able to read and understand the output to make sure it works as intended.

LLM's are a useful too for programmers to automate repetitive tasks but it is nowhere near bearing able to produce usable applications by itself. I am not worried that I'll be replaced by a robot anytime soon.

Those who should be worried about their jobs are people in places like customer support or government services directed at people who doesn't matter to the ruling class. In these cases the powers that be have little holding them from replacing human interactions with significantly worse interactions with a LLM. Nobody important gives a shit if some schmuck can't cancel their cable subscription or gets their employment benefits cut because the computer had a hiccup.
