It definitely wasn't a single prompt, but two hours of back and forth, with a lot of time spent thinking (me, not LLM) in between. There were multiple times where I misunderstood something, so if I just read a book I'd probably get stuck many times.
I've wasted a ton of my life already trying to make llms work for learning over the last few years, I'm especially bitter about it. I think this technology is a scam made to make us reliant on a think-for-me machines.
I have many times asked it something I was slightly curious about, got the answer after the first or 2nd-3rd prompt, spent 3 minutes in total and forgot it after 15 minutes probably.
But a few times I've spent an hour or more on a topic, asking many questions, thinking between responses, and I actually learned something.
Now, if I go back and forth with the LLM to say, taking the language learning example, to explore the etymology of the word (which for me is far more interesting than the translation itself), then I learn a ton more.
