Shopify Invests in Research for Ruby at Scale - https://shopify.engineering/shopify-ruby-at-scale-research-investment

Ruby is still untapped, as crazy as that sounds with the mad popularity of rails – it's such a friendly language, start simple, get as complex as you like

I always like to compare Ruby with Lua. Lua has a ridiculously tight, clean, simple design. Ruby is basically opposite, and yet optimized for a certain kind of ease of use that somehow mostly plays well with its messiness.
