I’ve seen teachers use this stuff and get actually decent results. I’ve also seen papers where people use LLMs to hack into a computer, which is a damn sophisticated task. So you are either badly informed or just lying. While LLMs aren’t perfect and aren’t a replacement for humans, they are still very much useful. To believe otherwise is folly and shows your personal bias.
Oppenheimer is a mainstream movie though. It’s not that geeky.
