It's clear to me Ruby/Rails ecosystem still has large productivity advantages that make it competitive in the market.
The line for years has been, developer time is far more expensive than machine time, so if productivity outweighs performance, then 🤷
However, I have wondered if the same thing holds true if profit isn't involved.
Now I'm considering that perhaps developer time is even _more_ valuable when there's no profit.
Hardware only gets cheaper, and Ruby keeps getting faster.
Why not both?
Though productivity and performance are not the only factors, I could see a time in which a language with similar values to what the Ruby community values but with far better performance reaches parity with the Ruby ecosystem for productivity - that would be interesting.
Maybe this will be Crystal, or maybe Ruby's JIT will catch up, or have the option of compiling to LLVM in the future, who knows?
