I don't think anyone is arguing that companies fail to grow because of these languages. It's merely that they would grow more quickly once at scale if they didn't have to spend several years rearchitecting while adding few innovations in the meantime (this is what happened at Twitter, for example).

Hmm, I didn't think it took any of them years to rearchitect per se? Regardless, somebody has to do it =) I for one am grateful for these giants pushing our current platforms and languages to their limits. On top of that, they've gone and found solutions, all in their own ways to solve the problem of scaleability. No?

It really did take twitter many years to rearchitect and break their most problematic dependencies on Rails, yes... my understanding is that it was a 4-year process.
