> You're still just arguing that Intel knew this would create huge vulns and they went ahead regardless, which is baseless.
The first scientific paper about such vulnerabilities namely in Intel processors is from 1995 [1]. They went ahead regardless. Processor technology has developed a lot. Many things that were not practically feasible in 1995 are possible today. That holds for the good and the bad. There must be some people inside Intel who must have understood that. Otherwise all that progress would not have possible. Some experts might have blind spots, but I doubt Intel microarchitecture is developed by just a handful of people.
The product being designed in 1995 was very different from today. Many of these trade offs result in much lower risk vulnerabilities in 1995 when you don’t have virtualization or hardware shared with anyone with a credit card.
I lack the technical expertise to honestly critique the architecture. My assumption is that the folks behind the design of some of the more advanced technology on the planet aren’t morons or seeking to defraud the market.
All of the noise here is about significant vulnerabilities that haven’t been exploited in public. It is a serious defect, but not the end of the world.
That paper primarily discusses a (cooperative) covert channel between processes using the FPU TS register, then mentions that caches or the TLB could similarly be used to implement a covert channel. IMO, meltdown and Spectre and MDS are a different class of vulnerability, so I don't know that I would say that paper was about "such vulnerabilities."
