Kinda off topic, but yeah, I love that video.
He's not entirely serious obviously, but not entirely joking either.
The appeal of JS definitely is it's ubiquity, but you have to draw a distinction between JS the language and JS the platform. Programmers always want to use the latest and greatest languages, but they also want a robust ecosystem and tools that come with a mature platform. So JS and Java both have great platforms, even though they aren't great languages in and of themselves.
Anyways, the mio rust crate isn't related to that Apple thing. Rust is a great language, but it's immature as a platform, so it's hard to find good libraries that do what you need.
