Lawrence Lessig's Keynote at SCALEX12:
I found a TED Talk by Lessig where his message is much more concise and a bit more entertaining: https://www.youtube.com/watch?feature=player_embedded&v=mw2z9lV3W1g ( 18 min )
His message is very important IMHO: Our escalating battles for a free and open Internet (and society) are mostly futile until we address the root cause problem of systematic undermining of democratic governments by special interest money.
I agree with Jono and Jeremy that it is hard to resist a sense of helplessness and resignation when confronted with this problem, especially with no clearly visible road-map to a solution. I suspect that many of us are increasingly feeling that way.
Lessig acknowledges the rise of this sense of resignation in his TED Talk but points out that our forefathers overcame bigger challenges, [ e.g. slavery, civil rights, gender discrimination ]. He offers more of a road-map in this TED Talk.
[note: this Lessig TED Talk is clearly focused on political problems in the USA, but has global implications due to the USA's disproportionate influence on the Internet and Western societies, deserving or not, IMHO]
