You talked about how you felt like Ruby was sort of the "hip crowd" so to speak, since enterprises hadn't discovered it yet. Do you feel like that is still true of Ruby? Is there another language that has taken that place in your mind? What would you choose to write Github in today?
I don't know that there's anything that feels quite the same at the moment. React has some of the feeling, except that it's enjoyed much faster adoption because of the Facebook backing. Vue seems to be more the underdog. GraphQL is another technology that's early but picking up a lot of steam (also thanks to FB).
Today I might do GitHub with a Rails/GraphQL backend and React frontend. Or I might try to stay with JS for most of the GraphQL backend but still do the heavy Git work in Ruby or C. I'd have to think about it a bit more, but the React/GraphQL/Apollo stack is pretty enticing to me today.
