This argument isn't even internally consistent, let along based on good predicates. He states that the better languages are the ones being learned. Then shows that Scala is the most popular language to learn ATM. He then states that you should use a language with lots of popularity, which he also shows to be Scala. Then dismisses it because there aren't many other companies using it, or developers who know it. Well, no shit: They're all busy using it and starting their own companies that aren't yet big enough to hire! I have a bias that states that people who use github, hackernews and learn new languages are better developers in general because they give a shit about their profession. By this articles hypothesis, those people are worth exactly the same as any other developer, when we KNOW that a good developer is a MUCH better developer then an average one.
