>What good does that bring if Apple shuts down the project?
How could they do that? They could cease providing the facilities the project relies on in newer chips, but the existing chips, er, exist. They could stop making chips all together and go back to intel. It's not a useful hypothetical.
>Also, I don't believe Apple has no backdoors and such. They basically made it impossible to be root on your iPhone, so you don't think they have a almighty-super-superuser mode on their laptops that only they can use?
It's possible such a thing exists, of course, it's possible on intel, or AMD, or any ARM chips, or any chip at all. However such a back door, if discovered, would not be accessible only to them. It would have the same problem that all such backdoors have, in that if Apple can exploit it, others can exploit it. Apple very heavily relies on the claim that they have no such back door, and they have relied on this as a legal defence, and frankly it's hard to see how they would benefit from having such a back door. A chunk of their business model and legal liability protection depends on not having such a back door.
>Wishful thinking if you ask me.
If you say so, this is all about relative risk. However what reason might anyone have for thinking that any other platform, such as Intel with it's proprietary supervisor code with remote updatability, is more under the control of the user? There may be platforms that have a better security architecture that's more under the control of the user, but I can't think of any of the major ones that does. Which would you suggest?
