I half agree with you. It's not so much that Linux lacks a clean driver interface, it's really that OEMs write shitty software that doesn't belong upstream. Ideally vendors stop writing garbage drivers and distributing hacked up kernels with their "sample code" (but ends up in production) and opaque binary blobs.

Android unified vendors but simultaneously made them even lazier. It's somewhat hard to get non-android code from vendors in the past 5+ years. Which makes me very sad.

Will Fuchsia somehow convince vendors to produce better drivers? I don't see how Fuchsia makes this problem significantly easier. Shitty vendors will continue to be shitty vendors and take the easiest path to making money.

In any case, the Kernel's super power is its community, not the software itself. The LKML is vast and full of knowledge, a strange intersection of open source, research and corporate exploits.

I don't see Fuchsia replacing that anytime soon.
