Where did he say anything about scaling in the article?

I was actually pleasantly surprised by not reading about the usual "webscale" BS in these two articles. Both authors made it very clear that this is not about being able or unable to build something with a given language, but the quality of how you do it.

It sure it, but that's not part of the discussion. Also, when talking about web development, the language used is rarely the bottle neck.
