Largely agree, though some things are notably difficult in some languages. Things like true concurrency for example didn’t come as naturally in Ruby because of the global interpreter lock. Of course there are third party libs, and workarounds though. Newer versions of Ruby bring it more natively, and as we’ve seen, Homebrew has adopted and makes use of that experimentally for a while, and the default relatively recently.

I can’t say that’s the only reason it’s slow of course. I’m on the “I don’t use it often enough for it to be a problem at all” side of the fence.
