Bill Gates appeared for the full hour on the Wednesday, March 3 edition of The Charlie Rose Show. It is well worth watching.

Hopefully, audio will be posted soon to the archives at charlierose.com. As yet, they are just selling the videotape, but most shows are available in streaming audio after a few days' delay.

It's a wide-ranging conversation about Microsoft, the Gates foundation, developments in biotechnology and other applied fields, and more.

While you're there, you may also be interested in a February 27 interview with Georgian President Mikhail Saakashvili.
