This was brought up the last time it was posted, to the extent of the post itself being given a confusing, clickbaity, editorializing title about Ken Thompson. But I don't see it as the same thing. Ken Thompson showed that he could hide a backdoor in a compiler where you'd think you could verify the compiler as safe, by reading its source code and even compiling from that source code, but in fact it was sneakily changing its own source code as it compiled it. This demonstration, on the other hand, is saying that they can hide a backdoor in a microchip, where you can't verify it as safe. The chip is not, for example, making the sneaky capacitor disappear when you use the computer to view schematics of the chip. I don't see where "trusting trust" is involved, just "trust".
