kalomaze calls ES/genetic-algorithm training pointless unless backprop is truly intractable

kalomaze · x · 2026-09-30

Researcher kalomaze argues that evolutionary-strategy / genetic-algorithm training has always felt boring to him — "Sakana-tier" in terms of pointless nerdsniping. His bar for abandoning backprop: only do it in regimes where naive backprop is intractable without BPTT, citing synth gradients / DNI-style work as the right kind of setting. A notable technical take in the ongoing debate over alternatives to backpropagation.
