Few of us have the time or money available to hang out at interesting symposiums and summits (nice to contemplate such a lifestyle though). Happily these are often streamed. Such was the recent “Humans to Mars” summit held in Washington DC. There was a great variety of speakers and topics. Three marathon 8+ hour videos cover the three days of the event. This sort of thing can be interesting to have running in the background as you work with “cocktail hearing” to alert you when favorite topics come up.
Lots of good material, and thanks to the uploader.
