Alright look with all the side channel discourse happening again I just need to say it: modern silicon design is fucking hard, as is security in general. At the risk of sounding like an Intel shill: chill the hell out. There is a lot more to this than a lot of you realize.

We spent the last 4 decades fighting the laws of physics to make things smaller faster and better, and as a result processor architecture is basically the same as it was in the 80s, but with Way More Stuff™. Does this make it ok? No, it's terrifying, but that's infosec.

We're at a turning point now where people are realizing that there's a whole new entire class of attack surface. This happens at least once every five years recently, and tbh it will get worse before it gets better.

Its hard to thwart an attack or shore up an attack surface you don't even know exists, and hindsight is 20/20. This shit may seem obvious now, but it took a lot of thinkers a lot of time to get here. The thing to do now is think about new, safer paradigms for moving forward.

Instead of adding to security theater noise and calling out specific groups, try to realize that this is not the fault of a specific company, it is the result of an industry filled with brilliance rushing to be the fastest.

Instead of all jumping on the bandwagon of unsafe approaches to being fast, AMD or ARM could have dumped 0day Spectre on Intel decades ago. Quietly following bad design was a choice.
