Ruby caught a second wind when they started putting effort into their JIT, which in our testing made it quite a bit faster than every interpreted language except JS in real world performance.

But then Python got a second wind in performance with better rewrite in Rust integration, but it looks like with the latest DHH keynote, Ruby might also go down that path.

My opinion is that I/O and concurrency ease of use and performance continues to be Ruby's weak point vs other interpreted languages. Which also happens to be Go's very few strong points.
