Aaron’s still at it, fixing bugs in bundler, nokogiri and maybe still teaching even. I’ve stopped using MRI because the toolchain and ecosystem aren’t conducive to economical scaling or profiling like C or JVM. JRuby is much easier to profile using JMX, but it’s harder to get native extensions going and not the same. For backend, lately I’ve been more in the Elixir/Erlang, Rust and Go camps for solutions.
SideNote:<p>There isn't much love left for Ruby in HN anymore.<p>RubyKaigi, Ruby 3x3 and Method JIT, Nothing Ruby lands on the HN front page anymore. Voting are also very low.<p>It was Rails that brought Ruby into mainstream and popularity, it was also Rails that people left Ruby.
