>And unfortunately ruby isn't powerful enough to do what Apple needs

If this was the main and only reason such that removing this limit Apple would have used Ruby, then why in your opinion didn't Apple try to implement themself something like RubyMotion (which was made by a company a thousands orders of magnitute smaller)?

RubyMotion author used to work for Apple. When Apple shut down their MacRuby efforts, he left Apple and started his own company to continue the work.

Doesn't prove anything about Ruby's suitability, though.
