Agreed; this is somewhat useful for beginners but incredibly silly for professionals.

I'm endlessly amused by the fact that among the first applications of LLMs were tools to summarise emails, accompanied by tools to write your emails based on a short description of what you want to say. So soon we'll effectively be communicating by text message, with the LLMs acting as a sort of anti-compression in between.

My brother lives in Japan, and he recently had to write a lot of emails to the company renovating his apartment. He said that ChatGPT was a lifesaver there since at least 75% of semi-formal (i.e. between customer and company) Japanese emails is formality and filler. He just skipped all of that and ChatGPT wrote it for him.

That's actually a very sensible use case!

I think the use cases are where you roughly remember the commands but not the full command. Like rather than you looking up a man page you could potentially use this. An expert in one field may not be in another, so they might also find this useful!
