The title of your self-submitted post is misleading. The bait post you're referring to stated the obvious, albeit in highly charged language.
It's one thing to choose the wrong language for a project. But having done that, please don't submit a post that suggests expert knowledge or deep experience in Ruby.
For what it's worth, I use both Ruby and C++. I would probably have gone with Qt if I wanted to build such a game. It would never have crossed my mind to write it in Ruby, and I don't consider myself an expert in Ruby.
Reasonable comments - thanks for the HN feedback. It's not for me to say if I'm an expert in Ruby or not, but I don't think attempting something to push some boundaries is mutually incompatible with experience or knowledge. If I'd succeeded, it would have been awesome for Ruby (far and away my favourite language).
