When stuff is the state of the art, then its “look” is nothing special, that’s just what things look like right now. There’s nothing inherently special about vinyl records in the 60’s. But later, when tech has moved on, people will look back and see the old tech for it’s unique qualities. Some people will find they like them as an aesthetic choice, rather than just accepting whatever the current status quo is. It always happens - there’s no photographic medium in the history of the field that’s totally gone out of existence. Hell I met a guy once who still makes albumen prints.

Add that those old cameras are dirt cheap, fairly easy to find, and much more convenient to use than other old techs (like medium format film, for example), and add a dash of nostalgia… Whats not to like?
