I have done this about mechanical engineering and manufacturing things that I know well. With some things, its answers are about as good as a decent overview article that you might find with google after sorting through a few spammy ones. With other things, it can make remarkably dumb mistakes, but as has been pointed out here (and elsewhere), it's possible to give it some corrections and ask it to do further reasoning. For instance, I asked it to list common defects in injection molding. It did a pretty good job of listing and describing the things that I'm usually looking out for. On the other hand, I asked it about how much a solid tire is typically stretched when placed on a rim (e.g. for an electric scooter). It came up with a typical percentage range, and then I tried to get it to reason out how the cross-sectional dimensions would change based on that stretching. It made several really basic errors that I managed to get it to correct, but in the end, I didn't really trust its ability and or "knowledge" in this area. I have found it to be pretty relaxing to use as a recipe source, since it will just give you a recipe and the basic instructions without the fake history and 17 ads. It's pretty good at taking some vague requests about having certain ingredients and wanting something in a particular direction, and giving a reasonable result. Maybe if I was an expert on cooking particular types of food, I would find its answers comical or pedestrian.
