> Because the ruby community generally revolves around rails.

Be careful about to which Ruby Community you believe you are speaking for. Keep in mind that a lot of development of the language itself is happening in Japan, in Japanese, where most people won't be regularly reading and posting on Stack Overflow. 5 of the core contributors live within 15 minutes of each other and meet and discuss issues in person.

If you've watched recent developments in the Ruby Community there, especially in the areas where the Ruby team has made large performance gains to improve the language, Embedded Ruby (as in Ruby running on IoT devices, or mruby, not ERB templating) is actually a very hot topic and isn't even in the orbit of Ruby on Rails.

Japan is still seeing growth in adoption of the language and has a huge number of Ruby conferences. There's multiple "regional" versions of RubyKaigi in Japan throughout the year.
