The First Machine Learning Demo Was a Mechanical Mouse Named Theseus

A viral history thread traced modern reinforcement learning back to Claude Shannon's 1950s maze-solving rodent — and to a naming coincidence worth savoring.

Amid the churn of new launches, a history lesson found an audience. @thelichhh noted that "the first machine learning demo on film is from the early 1950s," featuring Claude Shannon and a mechanical mouse called Theseus that learned to navigate a maze. The thread drew moderate buzz, in part for the obvious resonance: the field's foundational figure shares a name with one of today's leading model families.
