In the aftermath of the financial crisis, a person using the alias "Satoshi Nakamoto" invented “bitcoins,” a virtual currency users could trade for real bills like dollars and euros. His idea was to circumvent the manipulations of central banks and irresponsible governments. We talk to New Yorker writer Joshua Davis, who, in a recent piece, tries to find the real Nakamoto and examines whether bitcoins could do to real money what digital music did to analog recordings. Also, a Chicagoan explains why he uses bitcoins. Later, William Greider, national affairs correspondent for The Nation, tells us how he would break apart and re-imagine our dysfunctional economic system.
