Reinforcement-learning researcher. The vault first encountered him via a
terminology dispute over his 1984 PhD dissertation ("Temporal Credit
Assignment in Reinforcement Learning") and whether it coins the phrase
"structural credit assignment" — unresolved, see
[[question-verify-sutton-1984-structural-credit-assignment]]. He recurs
independently as the author of "The Bitter Lesson" (2019), the essay the
vault treats as the historical hinge between a hand-designed-vs-learned-kernel
myth and a cross-domain neural-scaling-law bridge, which is why he clears the
hub bar on a second, unrelated thread rather than one.
