No, it hasn't. You're confusing digital cameras with Polaroids.
Polaroids are much bigger but I've also seen a resurgence in crappy early digital cameras in young adult spaces. There's been a slow rise in all things Y2K in some spaces and getting a crummy digital cam from a thrift store or ebay is a sick find.
No, I’m not. Old digital point-and-shoots, and the harsh direct flash aesthetic, have been very popular. Some specific camera models that some random popular TikToker happened to recommend have been selling at quite a mark-up.
Two-ish decades is the standard length of a trend cycle. 00s is now retro in a cool way. Gen Z/Alpha, who have grown with phone cameras, want a different look, and having a real flash is particularly attractive because it allows taking reasonable photos in night clubs etc. Just like we did back in the day.
