Now, imagine the possibility that this is Intel's attempt at planned obsolescence, and that they're paying people to scrutinize their current chips so they can release expensive chips which are supposed to be "secure". Sprinkle in some FUD about AMD, and you have a perfect recipe to bump the prices up and get ahead of the competition. This is just my attempt to consider the wildest possible conspiracy theory, but I wouldn't be surprised if that turned out to be true, just like that landfill of E.T. cartridges in New Mexico.

My idea is that they could announce such chips in the future, and it doesn't even matter whether they'll actually be secure. The point is that they could be trying to pull off such a marketing stunt.
If they pushed so hard that their older processors were flawed, then this would be a PR hit for Intel as a whole, and it would orient more people to buy AMD instead than whatever new and "secure" chip Intel is selling later.
I mean, with what kind of straight face can they claim their new CPU is "secure" after their older processors were such a cesspool clusterfuck of hacks for the sake of speed while they still adamantly claimed "all is fine" and paid/bribed/NDAed companies to keep any bug or issue covered up?
