Now it's rust... who knows what will be tomorrow.
Meanwhile, the software that was originally written in C/C++ was 'yesteryear' rewritten in ruby, then rewritten in go, now in rust, tomorrow in whoknowswhat, and in the meantime, everyone still uses the C/C++ variant.
I think Go is here to stay, though.
Rust has primarily been used for rewriting existing stuff. Go has been used to produce new things.
That's not the only reason I think this, of course, but it's a small but significant indicator that experimental development is significantly easier in Go than the other static-typed languages.
Interesting observation. Coming to think of it, it might be true.
In Ruby/Rails, your entire team has to be an expert at it or you'll struggle. Even then, you can struggle with some spooky action at a distance idioms.
It is such a draining experience.
And I recognize that it doesn't have to be that way. But Ruby enthusiasts should recognize that it is common enough to have earned that reputation.
