All Watched Over by Machines of Loving Grace
I had this documentary pointed out to me by numerous people. It's a fascinating look at how the world's financial and political systems were affected by ideology, computers, and Ayn Rand.
It's simplified, obviously, but I agree with all of the major points. Absolutely fascinating. I'm very grateful to the BBC for producing stuff like this.
