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.
For better or worse, there's less friction now for seeing an answer to a question you have. You can ask in more arbitrary ways than Google required, and something will still come up. For looking up factoids, it's much faster. For picking up more complex topics, I'd say it's more or less the same, because you still have to spend time ruminating on the topic.
