(Though 90% is quite an exaggeration, the chances are high enough to warrant legitimate concern)
I think the current generation of AI is sort of between your number 1 and 2 depending on the user.
I primarily think of it as a pretty amazing search engine or way to get quick answers to questions that you cant easily search for. My next use case is to have it analyze my work - Eg a write up I made, some math I did and want to verify, a PowerPoint I made, etc. One of my worst traits is that I am only semi literate
grammar and spelling are fine (typos
we wont talk about that)
but I tend to provide more information than people want
.so, its great at trimming down my word vomit to all that needs to be said.
Straight up plagiarism
not so much for me
closest thing would be that I want to run an experiment with code that is not worth the time if I am going to spend days coding up when I have only a small bit of confidence it will be useful
if I can give it proper instructions, it can code it up very fast for me and I can run the experiment that way
that is worth it. The value is in thinking of the experiment rather than grunt work of coding it up which ai is great for. In production, I would be far more cautious.
