Rails developer here. It's still quite easy to get a Rails job; maybe not for Google, but easy. There's much less hype but also less competition over jobs (many young developers come with Python/Nodejs backgrounds nowadays, many senior Rubyists left for greener fields).
As for rails? Admittedly I'm in an anti-ruby bubble... but the Ruby developers I do know definitely don't use Rails anymore. Ruby seems to have matured into basically just Chef/Vagrant in my bubble and any Rails apps are being deprecated in favor of the bubble-biased languages.
