Again, consider the positive side effect. If several computers are rendered useless, we get more bookends and people start to collect and read more books, instead of consuming crap. I'm a 51 years old dyslexic, but you still find more read scientific books in my flat, than in many other flats of my generation, let alone the younger people. While Meltdown and Spectre are a disaster for a lot of server farms, it actually is unimportant for zillions of other computer usages. Meltdown and Spectre are not Fenrir [https://en.wikipedia.org/wiki/Fenrir], we were much closer to Ragnar=C3=B6k [https://en.wikipedia.org/wiki/Ragnar%C3%B6k] when we were affected by Heartbleed, but actually we survived it without much wounds. Don't belive the hype [excepted of the song's title, not really realted :D https://www.youtube.com/watch?v=3D9vQaVIoEjOM]. --=20 https://www.schneier.com/blog/archives/2018/01/spectre_and_mel_1.html
