Let’s take vim and emacs, or bash. People do not spend years on them only for pleasure or fun, it’s because they’re trying to eliminate tedious aspects of their previous workflows.
That’s the function of a tool. To help do something in a more relaxed manner. Learning to use it can take some time, but the acquired proficiency will compensate for that.
General public LLMs have been there for two years, and still today, there are no concrete uses cases that can have the definition of tools. It’s trust me bro! and warnings in small print.

There are some, but you won't like them. Three big examples:
a) Automating human interactions. (E.g., "write some birthday wishes for my coworker".)
b) Offensive jokes and memes.
c) Autogenerated NPC's for role-playing games.
So, generally things that don't require actual intelligence. (Weird that empathy is the first thing we managed to automate away with "AI".)
