Why would Ruby developers be getting more scare? Are they retiring earlier than Java developers?

> Why would Ruby developers be getting more scare? Are they retiring earlier than Java developers?
Ruby developers have always been a tiny fraction of the number of Java developers, and that fraction has been steadily decreasing, while the Java developer pool keeps increasing (Android helped quite a bit growing that population).
Benchmarks these days show Ruby 1.9/2.0 as being a wee bit faster than Python, and it's improving. That's still much slower than Java, of course, but then that's a bad comparison; Ruby and Python are better comparisons.
Not just that. They reject Ruby because
1. It's very slow and continues to be very slow despite all the performance work being done on it (nod to JRuby).
2. It's just hard to hire Ruby developers, who are getting more scarce every year.
These are the symptoms of a dying language.
