"Rails at scale" is a funny title. Shopify had to rebuild the core parser. Github has a department dedicated to working off the bleeding edge of Rails (and has core Ruby and Rails maintainers on staff, Shopify probably does too). Both Shopify and Github spent literal engineering years upgrading Rails, and still for some reason think it's worthy of boasting about in engineering blog posts, despite the burnout, not-shipping-features, and turnover they suffered because of it.

If your company has enough engineering overhead and capacity to stop delivering features and try to fix your core language for a year, then you're in a different ballpark from most other tech companies. If you're NOT in that boat, then "Rails scaled for Github and Shopify" is not a message you should take home.

If you're not in that boat, odds are you don't need to care.

And they didn't stop delivering features for a year.
