[dualogy]

Sounds like a super-worthwhile, valuable & lives-enhancing (or even saving in some cases perhaps!) idea to me.

Your lesson here then: Dont ask people to judge your ideas, unless they're themselves full of good ideas often (in your estimate). Whether family or friends or anyone is irrelevant here on principle.

Here's another ai-but-not-gen-ai idea: app to see how one would look with some specific haircut, from multiple angles or ideally from all angles (feed enough photos for a good-enough "3d skull detection"). One could show their haircut choice rendered in-app to their barbers, and/or barbers could also subscribe to such an app to offer the feature to their present customer, perhaps by live-filming their head for a few seconds. (Something I'd like to exist but not badly enough to make it happen, compared to my other pursuits.)
