This is what the guidelines mean by "generic tangent", "shallow dismissal" and being "curmudgeonly". The comment is not about the project or topic, it's just a general expression of discontent with things related to the project, without any consideration of whether that pattern applies to this project or whether this project may in fact be an exception to the pattern.
Please avoid comments like this on HN, and make an effort to observe the guidelines.
I'll join your demise! I have a similar opinion and came up with my own answer.
Ruby is effectively Rails. Something about this has always bothered me because I don't like ruby and it gets SOO much praise from users. Which all almost universally happen to be using Rails. I've never used rails so I could not say why authoritatively. I did find someone recently on here that talked about it and mentioned that Rails is steeped in "magic". That it is unbeatable for a single person founder to create a project of any size. The problem is all that "magic" becomes a huge point of contention/confusion/friction when non rails zealots get involved, which is basically everyone.
Or to be more to the point Ruby and rails has a very specific use case and that use case has nothing to do with the application you are building rather the type and size of Team you are assembling.
To me its just a more obscure Python with a much smaller more enthusiastic user base.
The only Ruby tool I (knowingly) use is homebrew, including distributing internal tools at my employer via private taps. I feel like migrating to nix would be a hard sell, so I'm hoping homebrew isn't on its way out just yet!
