It's like writing a book in ancient Latin. Sure, you can do it, but there's words missing for pretty much everything that was invented in the last four hundred years.
Ruby is a fantastic language and it's good to see it remains popular.
One thing to add is that JRuby is a huge game-changer for Ruby. It gets rid of the "Global Interpreter Lock" and means your Ruby code can now take full advantage of ridiculously multi-core systems if your workload can be run in parallel.

On the "What languages do developers prefer by age?" chart it's inexplicably second.
Also utterly baffling is Swift, which is a great language, seems exceptionally popular with the 55+ group. This data is highly questionable.
