      First read of the AMDFLAWS whitepaper (no real technical details given) is: “over-hyped beyond belief”. This is a whitepaper worthy of an ICO. And yes, that is meant to be an insult.

      • Report NetzDG Violation

      It begins with a statement which is clearly set up for financial readers as they quote the FTC and by page 2 it is a flurry of mediabites (“bad actors”, “espionage”, “disregard for fundamental security principles”).

      But the footnote? Ha, it is a link to AMD’s very own “Aerospace and Defense Applicaiton Brief”, i.e. a *marketing document*. There is zero chance that they are already installed anywhere, the dev cycle is decades-long. They then throw self-driving cars into the mix except they...
