If we're unlucky, the 'black swan event' will be something along the likes of Pluto's Kiss. Imagine a Morris worm equivalent, but which bricks the computers it infects after destroying the filesystem.
Even if everyone has backups of everything, offline, it'll be years before all the destroyed computers can actually be replaced. This isn't a scenario I want to happen for real.
"BIOS PSP Support disabled" is the only statement we have, in the form of a new option in the BIOS Setup.
That sounds like the equivalent of "HECI Disabled" for Intel BIOSes, which has been around for years.
It doesn't do anything to shut down the hidden CPU (PSP). It just sends a command to disable the bridge over to the main CPU. All the other ways of talking to the PSP remain open.
I also hate Intel and AMD for that, but I think they'd prefer we didn't hate them. I conclude that there are big reasons to still do what we hate them for. I'm afraid even a black swan event wouldn't make those reasons go away.
What I think needs to happen is for other countries to realize this issue is a matter of national security, and to fund development of alternatives.
Well, I will not buy an Intel CPU anymore. I also try to avoid Intel in all other chip classes like networking chips where Intel is suspiciously active. Sometimes I wonder if their name is giveaway that people just don't realize. Soon I intend to move to an Intel-free single board computer for my day-to-day computer usage. Now, for other people I can't speak.
I absolutely hate Intel and AMD for sabotaging their customers like that. Please people, get to that black swan event ASAP.
