It'd be great to see that change over time, but to be honest I'd be more excited to see some movement behind the crystal lang, because I love coding in Ruby. All of my side projects are now being written in Ruby because I don't need something that scales in microseconds, or 10's of milliseconds for that matter, and I feel so much more productive.
Again, I hope I'm proven wrong. I think Phoenix has a lot of potential, but it still has a long way to dethrone Rails.
