This. I dont really need true essence of metaprogramming craziness of Ruby. I need Ruby-like, dev happiness, readability and performance. Wish Crystal would catch up and get some attention.

Kotlin is very ruby-like and performant, check it out. If you don't mind using JetBrains IDEs, I'd give kotlin a try.
