I had an example recently: I wanted to learn more about how certificate-based WiFi authentication worked. In the past, I would have used Google to find some resources on it, probably find that the relevant standard is called 802.1x, used Google to find the relevant Wikipedia article, skimmed that, etc. But instead of doing that, I just asked ChatGPT the specific questions I needed the answer to.
When you're asking generally about a pretty basic topic which you just happen to not be very familiar with, ChatGPT is not too dissimilar from having an expert in the field you can chat with and ask questions to. I find it to be a very effective way of querying the huge database of information that is its training dataset.
Surprisingly, the one thing it's really terrible at but which I would've expected it to be okay at, is writing config files. I sometimes ask it how to write, say, a systemd service file which does a particular thing, and it usually shows me something which looks roughly sensible but doesn't actually do what I wanted. Its nature of fancy autocomplete with no understanding really shines through in those cases. Its biggest downfall is that it has no way to recognize when it doesn't have an answer and is making stuff up.
