The point where you are having scaling issues because of the language then you are really going to be past the worrying about bootstrapping/hiring stage.
It sounds like you are spending time/effort worrying about scaling way before needed. If you can solve your problems you have today faster then I would do that, not hinder yourself today for possible problems way down the track.
Very valid point there dude. I don't know dude...maybe I just want things to be efficient right from ground up...Or it could be the after-effects of falling in love with Functional programming in Scala :)
