I mostly agree with this, after using Node the last several years. IMHO the primary valuable components are making it free to implement the commenest kinds of concurrency correctly. I.e. most programmers don't even know they are doing it, other than "Oh I have to use `await` here". Even in something as simple as Go, you still have to intentionally set it up. And in Java, I run into very slow very low volume apps all the time because programmers don't realize they added a blocking call somewhere.
