Lesson: Monocultures, like monopolies are bad, mm'kay?
Solution: Push for more widespread adoption of alternative CPU architectures, so in the future, these kinds of bugs aren't as dire. POWER, MIPS, are RISC-V are all available RIGHT NOW and great in their own right, just not readily available or feasible in many applications. Thanks to intel an overwhelming majority of our compute infrastructure is vulnerable and will suffer heavily for putting their trust in them
