Geoffrey Hinton is giving an SCS distinguished lecture right now. The room (WeH7500) is (or... was) packed. There are probably also people watching the simulcast in WeH5409. This time, however, a research group has also set up a computer to the video infrastructure, and is streaming the lecture over the network; several people are watching it that way, in the comfort of their labs (or, probably, through the VPN stuff, at home if desired). And I'll probably end up watching the video when it goes up online. Classic.
