I meant to say vim is the "hip" thing, as in, it's in fashion with a certain type of programmer for some reason. Fashion definitely exists in our world, even though it's hard to admit. In my (purely anecdotal) experience, vim gets a lot more lip service than actual use.
I use Emacs and this is completely anecdotal, but I agree, it feels like vim is the hip editor. I think it started to become hip when Rails gained traction. A lot of screencasts using vim. I guess this was when TM had fallen out of favor or something.
A lot of Elixir devs use vim, as well, and many came from Ruby/Rails.
