Compared to Rust, Go. The list of improvement for a yearly Ruby version is rather small. Some will argue Rust and Go are relatively new, but there are actually LOTS of low level performance improvement done within a year time frame.

Even if you compared to Python 3, the improvement is still rather small.

I know there is always the argument about the lack of resources, and Rust is being backed by Mozilla while Go is being backed by Google. But what about Python?

Exactly how much money is Mozilla spending on Rust, paying how many developers full time? Apple JS Core team is incredibly small, but they manage a B3 JIT compiler with 2 people.

How much money is needed? Matz and Tenderlove both mention they need more resources. Surely we can fund rise? With lots of successful companies using Ruby on Rails. Basecamp, Twitter, Groupon, Github, Gitlab etc. Or Ruby communities lack the compiler / JIT expert, can we hired some?

I am not trying to downplay the Ruby improvement. But I think Ruby needs more contributors. Moving to GitHub to get a higher exposure has been banned due to GitHub not being an opensoure product. But they also dislike hosting on Gitlab for some strange reason.
