Walk of life

摘要

Humans have a strange response to things that are lifelike, but not alive. It makes some people profoundly uneasy. Think of waxworks that-look almost - but not quite - like the people they're modelled on. Think of animated films where the characters look almost human, but their skin is too waxy and the eyes are glassy. It's known as the Uncanny Valley, and to watch the videos of Boston Dynamics' robots is to take a trip into its depths.
