Brain has 200T synapses yet forgets a penny; a 20T-param LLM forgets nothing
fleetwood___ · x · 2026-11-14
An interesting contrast: the human brain has 200T+ synapses versus roughly 20T parameters in a frontier LLM — yet humans can't recall which way Lincoln faces on a US penny, while an LLM remembers every abstruse detail. A reminder that memory capability doesn't scale simply with parameter count, and biological and artificial memory differ fundamentally.
