These beliefs depend on this one:

• IN backprop-fragmented-discovery-history — Backpropagation was independently discovered at least three times across 16 years — Linnainmaa (1970), Werbos (1974/1982), Rumelhart/Hinton/Williams (1986) — making it one of the most multiply-discovered algorithms in computer science.
