Yes, but humans will eventually get used to it and internalize the keyboard, the domain language, idioms and so on and their context gets pushed to long term knowledge overnight and thei short term context gets cleaned up and they get bettet and better at the job, day by day. AI starts very strong but stays at that level forever.
When faced with a really hard problem, day after day the human will remember what he tried yesterday and parts of that problem will become easier and easier for the human, not so for the AI, if it can't solve a problem today, running it for days and days produces diminishing returns.
That's the General part of human intelligence -- over time it can aquire new skills it did not have yesterday, LLMs can't do that -- there is no byproduct of them getting better/aquiring new skills as a result of their practicing a problem.
