This brilliant article argues that current computing problems (such as Spectre and Meltdown) are caused by modern CPUs exposing a fundamentally different abstract machine than the actual computing architecture, mostly to satisfy the complacency desires of C traditionalists.https://twitter.com/CompSciFact/status/991687650389233664 …
Yes, but the main issue with the current vulnerabilities is that the CPU pretends to be in a fundamentally different execution state than it actually is, and it cannot keep this illusion consistent without sacrificing the performance gains.

That's only partly true. Intel screwed the pooch with Meltdown, neither AMD nor ARM did.
