I propose a corollary to the author's thesis: a languages popularity is a function of runtime advantages and time to implement an MVP for your domain. This corollary explains the scripting language conundrum: Python is popular because it's easy to implement an MVP in a number of different domains. Rails helped Ruby to achieve widespread use because it made it easy to implement an MVP for a web application. I think it's fair to say that to gain adoption, a language needs either a killer runtime or a killer app.
