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.

E.g. decentralized services like mastodon, or my own little ARM home server - since there's no profit, I need to squeeze all I can out of that hardware.

This in mind, I tried to build something simple in Crystal and wasted an insane amount of time shaving yaks and gave up. I'm sure I would have finished the project in Ruby in the same amount of time - probably partially because of my familiarity but more because the libraries are so much better.

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?
