If you’re a shop that churns through juniors, LLMs may match that. If you retain them for more than a year, you rapidly see the difference. Both personally and in the teams that develop an LLM addiction versus those who use it to turbocharge innate advantages.
I have had the unfortunate experience of having to work with people who have got a lot more than one year experience who are still worse than last year's LLMs, who didn't even realise they were bad at what they did.
