These days I regret to have Intel CPUs and to be happy to did not shredder the Atom N family. I also dream of LGA, AM4 replaceable CPUs out of their sockets (all mobiles devices out, desktop/server only). What if we only buy the cheapest CPUs in the future to reduce loss of throwing away all of them at once?
Selfdefending CPU with an AI-based ring of entry gates guards around all the time requesting my live FaceID with FLIR detection for if-I-am-alive before letting-in any high-level microcode to change the kernel? If you cannot defend the crown you lose the jewels.
Security is sometimes not a process, its just black-or-white (not to be mixed with reasonable overreaction). To understand the true reality about Meltdown/Spectre it needs at least three layers
1) be proficient in CPU kernel matters (SGX, TrustZone, Secure Enclaves)
2) understand the recent history in worst of hacking
3) face reality to not buy CPU-based hardware for 6-12 months (earliest 2019)
4) all other lost aspects
What is the new bright horizon to focus on? Not new CPUs.
Something has to change. This for sure.
