Severity: High Mood: Expected

Here we go again with the endless circus of processor flaws, as Branch Target Reuse brings fresh Spectre v2 misery to Intel, AMD, and Arm chips alike. The delightfully persistent leak preys upon JIT compilers in our web browsers, language runtimes, and the core operating system kernel itself. Insulating our poor infrastructure from these microarchitectural leaks means enduring yet more soul-crushing mitigations that will inevitably cripple system performance. Why do we even bother buying hardware when the silicon cannot hold its tongue?
