So there is a huge gap of perception of IA and LLM betweet tech people and other people.

You are correct that there are reasons tech people are more inclined to like these things, but it’s not really because AI is useful to them.

Actually, here’s a good video about its usefulness.

I think the reason tech people are so bought into it is a combination of

• their careers depending on them liking the new tech thing,
• a general sci-fi inspired enthusiasm for what can be accomplished,
• a dash of everyone here being an introvert with no friends,
• and the misconception that, because they can engineer something, they are smarter than the people around them.

That last bullet, I don’t know if you remember the contemptuous rivalry between stem majors and the arts or humanities, any major that was less “useful”—that’s the exact smug attitude I’m talking about. There are a lot of people who think they could just program away life’s many problems.
