I was recently looking at VR & AR devices

(As an aside: Because the res has improved enough where I can code, and the peak coding position is with a pants keyboard on an inversion table -- very suboptimal for a monitor)

I noticed all of them sans apple run Android.

I understand why Android has become the unfortunate standard for mobile, but it seem absurd to me that it is now taking over VR (as well as "IoT" devices, car computers and so on)

It seems like a very inelegant OS that essentially committed itself to the wrong paradigms in everything:

- Committing to JVM usage instead of supporting static compilation -- locking itself in a dead ecosystem that can't see the light of either Rust or simple scripting language - Having heavyweight security abstraction that don't really achieve much beyond a linux kernel - Dependant on a bunch of proprietary modules for <anything> - And (now) having a bunch of new features rooted in backwards compatibility hell

I can't even comprehend the monumental effort to get the sort of GPU-intensive and RT capabilities a proper VR experience requires running onto something like this (vs a minimal RT focused linux distro)

Am I just being unfair to android and missing a core benefit? Is it mass psychosis ? Am I missing an underlying reason why it's getting so popular ?

(To be clear: I assume vision OS is bad, given that it's apple, it just confuses me why e.g. meta would not develop their own OS)
