the researcher's note

Spectre/Meltdown as a loss against learned branch prediction. Effect verified (arXiv 1807.08703: mainline kernel slowed ~15% without and 21% with User-Based Firewall; ~50% on local disk; 21% pMatlab and 16% TensorFlow with all mitigations). Missing: a people.n from a fetched source — no primary count of affected CPUs — and no source attributes the harm to the learned component. Meltdown is out-of-order execution (hand-designed); only Spectre v2 targets the history-trained predictor. Held out rather than guessed.
