1. LLMs can't watch over someone and warn them when they are about to make a mistake

2. LLMs are obsequious

3. Even if LLMs have access to a lot of knowledge they are very bad at contextualizing it and applying it practically

I'm sure you can think of many other reasons as well.

People who are driven to learn new things and to do things are going to use whatever is available to them in order to do it. They are going to get into trouble doing that more often than not, but they aren't going to stop. No is helping the situation by sneering at them -- they are used it to it, anyway.
