It's still at the mercy of Apple, Intel and all the other opaque firmware vendors and microcode updates. Plus, it's not nearly UNIX enough, the damn linker doesnt do linker scripts so good luck developing non-xnu kernels without compiling under something else. And the sources aren't always released in a timely manner. Why is Apple still not open sourcing more of the OS?

In the future, I'd like to be able to choose a design of laptop or tablet online, modify it, choose an open cpu core and so on and create an entire, beautiful computer at home. Not everyone will want to do that, but I think enough people will realize open source hw is the future especially in terms of supply-chain security and reducing or adding features. (More broadly: How cool would it be to have company-specific devices, designed and built just for them?)
