There is also an adoption curve. The people that grew up without it wont use it as much as children that grew up with it and knowing how to use it. My sister is an admin in a private school (Not in USA) and the owner of the school is someone willing to adopt new tech very quickly. So he got all the school admin subscriptions for chatgpt. At the time my sister used to complain a lot about being over worked and having to bring work home everyday.

2 years later my sister uses it for almost everything and despite her duties increasing she says she gets a lot more done rarely has to bring work home. And in the past they had an English major specially to go over all correspondences to make sure there were no grammatical or language mistakes that person was assigned a different role as she was no longer needed. I think as newer generations used to using LLM for things start getting into the work force and higher roles the real effect of LLM will be felt more broadly as currently apart from early adopters the number of people that use LLM for all the things that they can be used for is still not that high.
