The best that current LLMs can do is PhD-level science questions and getting high scores in coding contests.

Your job? Might be secure for a lifetime, might be gone next week. No way to tell — "intelligence" isn't yet so well understood to just be an engineering challenge, but it is so well understood that the effect on jobs may be the same.

Tbh, your job is secured as long as your boss is not brainwashed and FOMO by the infinite cash burning and lobbying to sell LLM as the all solving holy grail. Depending on how long it takes to brainwash all leadership into thinking, LLMs can do your job(despite reality, I mean it takes some time to fail and then additional to deal with sunk cost fallacy). One of my colleague went to work for a startup that promises to replace ALL general practitioner/family doctor within next 2-3 years by LLMs. While I hope they badly burn and go bankrupt, I am also worried about the future as this particular startup is also getting major backing from certain big deep pockets.
