Seriously, some of the outright hostility I've seen in the iOS development community is breathtaking. Yes, there is a lot of money to be made in iOS development so, no, you probably don't need to practice community building in order to be successful...today.
Regardless, your snide comment about "Rails engineers" reveals your own ignorance on the subject. There are plenty of software engineers that use Ruby but not Rails, and any developer who cannot use Ruby without Rails is unlikely to be of any threat to "redefine iOS development culture", since RubyMotion is not Rails.
Edit: Also...since when have "hacker" and "respect for knowledge gained over 20+ years" ever had anything to do with each other? Take the "knowledge gained", evaluate it on its merits, and if you find it lacking, who cares over how many years it was gained?!? If you think you can do better, do so.
