If you really want a blog post to describe how JavaScript is eating the world, I suggest it isn’t “Beating the Averages” by Paul Graham.
It’s actually “Worse is Better” by Richard Gabriel. I don’t think people are writing JavaScript tooling while saying that JS is just as powerful as Haskell or Lisp. What they’re saying is that its ubiquity is valuable and for their use case, ubiquity and network effects trump productivity and/or “power” however we might want to define them.
