Amazing work and really appreciate all you're doing to better the ecosystem.
Question: (a) do you believe we'll ever get to a day when TruffleRuby/Graal will be able to 100% run Ruby on Rails and (b) how much faster over MRI do you believe it could achieve?
Compatibility yeah I don't think there's any reason we can't be very close to 100% there.
For parts of the Ruby ecosystem running production workloads, such as the Liquid template engine, I see 6x performance today. I think that's a realistic goal in time.
