I can't argue with the claim "If somebody is using something, they must place a nonzero value on it." But it seems a lot weaker than what the article says, and it's not even related to the Twitter conversation you linked, which was about the relative qualities of programming languages.

This restated thesis could be 100% true and it still wouldn't mean that the dominant programming language isn't the worst one ever invented.

And a language with nonzero value could still be effectively worthless — if Language A is worth 1 Foo, Language B is worth 10000 Foo and Language C is worth 15000 Foo, then choosing Language A means you lose more (relative to the others) than you gain.
