A Google Tech Talk by the author of Kilim, a Java library for lightweight actor-style message passing. It argues that message passing can replace shared-memory concurrency and claims performance competitive with or better than Erlang for huge numbers of actors.

Karl Sims's 1994 demonstration of evolved virtual creatures: block-bodied creatures whose bodies and controllers are evolved through selection, mutation and recombination to swim, walk and compete.

Andreas Antonopoulos argues that money has a fourth function beyond store of value, medium of exchange and unit of account, which is as a system of control. He covers the history of money and why it does not flow freely.

A one-minute clip of Steve Jobs at the D3 conference in 2005 discussing virtual reality. He compares VR headsets to headphones for video, an analogy later applied to Apple's Vision Pro.
