Maybe my impression on Vert.X was misplaced. Trying it out left me off with "Oh, so kind of like ANC minimal API with Rx.NET but faster". I should revisit this,

Maybe my impression on Vert.X was misplaced. Trying it out left me off with "Oh, so kind of like ANC minimal API with Rx.NET but faster". I should revisit this, thank you. JVM ecosystem has other great frameworks like Active-J and Ktor. My main point is, unless that's what you're most productive in, RoR is a really poor choice for both small and large codebases and there are plenty of options that completely eliminate the classes of issues you would otherwise have to spend the time on. Sure, I like using C# (and recently F#) a lot but it wouldn't kill me if I had to use Kotlin/Java/Go/Swift instead. All these have understandable tradeoffs and merits to them. On the other hand, my experience of interacting with advocates of Python, Ruby and Erlang is incredibly poor - it's impossible to have a technical conversation and it seems that their communities live in a bubble of belief that using interpreted junk comes with magical productivity advantages inaccessible to expressive modern compiled languages with rich type systems and excelled back-end frameworks/libraries.
