If I should disable hyperthreading because of a hypothetical risk from an experimental proof of concept, shouldn't I also throw my PC into a dumpster because I don't know if the microcontroller controlling my LCD isn't also amplifying and Van Eck'ing my desktop to Chinese and Russian superspies waiting in a van outside?

After all, I'm not _SURE_ I know what it's doing.

Perhaps you don't particularly care about that risk, or you don't feel the risk is plausible enough to warrant the loss of one's computer, which is fair, but the risk is there nonetheless.

Why would a l33t haxxor waste their time on an esoteric and academic attack when they can just get their victim to click on something?
