"Well, if you were to ask me whether I think a group of teenagers is smarter than a chimpanzee"

Well, your example was training a chimpanzee to do it vs. can teenagers use it without training. And I think they can and maybe even think it is cool, but unless you want to harness that coolness retro factor it makes 0 sense to use a rotary phone for actual use. It is way slower and therefore less efficient. But of course it would beat a modern phone that just looks cool, but only randomly works.

Which would be my requirement for any tool. Functionality first, looks second.
