As a server-side tool it has been getting taken over by Ruby/Rails, Python and the stuff mentioned in the OP.
I hope you are kidding here, because that is far from the case. Java is still the de-facto language for most server-side applications. RoR never outgrew it's hipster background. It has been 7 years since RoR had it's hype peak... The hype waned and RoR is still a rarity.
For God's sake, stop researching for a while and begin to think!
