The author has the boldness of saying that anything that does not produce a single artifact (golang binary or fatjar) is a language that should not be used an that they were errors of the past and we should get rid of them (citing explicitly PHP, Ruby and Python). Now, if we want to think that languages and whole ecosystems (libraries, bugs and edge cases fixed, developers and companies whose code base is written in such language) can be changed easily, then the author take on Docker is right. In such a world Docker doesn't add anything useful. But the real world is quite different and it's not going to change for the author, so Docker (or "containers") is still adding something valuable and it's not a "bet" to me, at all.
