Can we PLEASE stop acting like letting people keep their own money is somehow the same as the tax payers giving money to "the ev0l rich"???
Fine. If that's the case, would these "evil rich" do us all a favour and pay for the overwhelming publicly funded protection they get?
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.
