> One big challenge it addresses is Linux’s driver problem
Android devices have been plagued with vendors having out-of-tree device drivers that compile for linux 3.x, but not 4.x or 5.x, and so the phone is unable to update to a new major android version wit ha new linux kernel.
A micro-kernel with a clearly defined device driver API would mean that Google could update the kernel and android version, while continuing to let old device drivers work without update.
That's consistently been one of the motivating factors cited, and linux's monolithic design, where the internal driver API has never been anything close to stable, will not solve that problem.
