I agree on your analysis of the BC exchanges behavior. They neither did a proper risk analysis nor did they build a systen designed to safely handle the wallet nor did they respond in a timely and responsible manner. I just fail to see how that's rails fault. Would a bank run their OLTP on rails? I don't know. I'd rather say that rails is a bad fit for that kind of problem, but that's not the goal. Rails is built for web-applications of a pretty specific type, quick build and release cycles while still keeping a solid focus on code quality [1]. So your problem is that folks see an opportunity to make money, take the first tool that seems to fit and build stuff that doesn't hold water. But that's language agnostic. You certainly realize that 10 years ago java was the "poorly specified rickety language in a community of hype". [1] I never dreamed I'd be defending rails. gosh.
