I wonder if Shopify will ever give up on trying to fix Ruby and instead, do what FB did with PHP and just create their own derivative (Ruby) language that addresses their needs better.
Facebook has far more employees and wasn’t going to get PHP improved to their liking.

Look at PHP 7.2 onwards, which is a similar timeframe, and the improvements are fairly modest.
