I choose not to think about it or include it in my mental threat model, the same way I choose to not worry about thermonuclear warheads.
If there’s some exploitable backdoor and Intel gets owned, we’re all boned and there’s nothing we can really do about it. I don’t have anti-ballistic-missile systems, and I also don’t have the capability to make an entire hardware/firmware/os from scratch.
So instead focus on the things you can control and are more likely to happen. Don’t plan for doomsday, plan for every day.
My grandfather had a stroke at 81. He did not in fact become an asshole, he just got a little slower and spent less time working on his old truck. This is 100% on fetterman for having shitty opinions and being bitterly dug in. I don’t think it’s fair to all the wonderful people affected by strokes to give him that out.
