Smaller companies can be happy with Ruby as it is while enjoying the incremental improvements. They're hardly going to invest in hiring C-proficient engineers to bolster the language - it's simply good enough to start a business from and the performance metric is low priority.

They're in a different class to heavy hitters like Shopify and Github, who will gain a lot more from investing in gradual improvements to Ruby's runtime at the scale they operate at.

I'll contrast it with JavaScript, which has tried to assimilate every language pattern under the sun over the past decade and is intensely difficult to maintain a stable stack with, even if it's better now than it used to be.
