Of course some would, but in a world where they never existed yet it would be a sort of fantasy wish. As an example where we are on the other side right now, people are trying to figure out how to make beverage containers out of paper. Not coffee cups, but longer term storage so you might buy a 6-pack of carbonated drink in a paper "can" vs metal or plastic. Never mind if you or I think that's a good idea, there are people working on it and some day it might come to be and people might think it's great for whatever reasons. My point is that the masses are not clamoring for paper cans today because they don't exist yet. Likewise, before the advent of non-stick pans, people weren't demanding them because they didn't know it was possible. That's all I meant. So no, I don't think people were seriously asking for non-stick pans prior to their invention, they simply lived with what was available.
