Dunno. I think for a startup it makes good sense to have a dynamic language with a good package manager. For someone writing something which needs to be performant, and the requirements don't change too much, C is probably a superior choice. It's all about tradeoffs IMHO.
Except that the averages ended up beating the nerds, which is empirically observed by glancing at today's most successful and widely used software; and Lisp today is a fringe idea with its most popular implementation being a JVM transvestite.
As for Javascript being an acceptable Scheme, I'm personally happy to see it merely running in the browser and the servers of a bunch of SV startups, where it cannot do harm to society.
