Example: I want to buy some construction material that I've seen somewhere. I don't know what to search for since I don't know the term. Prior to LLM, the only way was to ask someone familiar with it, e.g. a plumber. Now I can ask GPT. And then I just do a quick image search to verify.

This doesn't always work, as some stuff is harder to verify. But what's valuable to me is it allows me to ask a vague question and have follow-ups. I usually learn just by having the conversation.
