Ruby is incredible. It is still one of the best choices for a platform to build a company or a product quickly with. If it cannot keep up with your scale, throw more hardware at it and it will still be worth it in terms of time and man-hours saved.

I only ever wanted compile-time linting and better autocompletion such as in the case of Elixir LS. Does something like that exist for Ruby now? How is Crystal these days?
