You're quite right in your counter-point. And besides it's not always clear beforehand what the key issues are going to be during a politician's term. I reacted more to the wording "Just because they are born in US doesn't make them responsible for the actions of the US military any more than someoe born in Canada, Brazil or Japan." I'd say US citizens are more responsible for US military actions than Canadians, however this definitely does not make the ordinary citizen responsible in the same way as an army general or prominent politician.
Wolves do fairly well without humans, bees as well. Which animals did we bring back from the brink of extinction? I'll admit that new subspecies have emerged thanks to humans, but we hardly need to keep e.g. 1.3 billion cows (https://en.wikipedia.org/wiki/Cattle#Population) just to save the species from extinction.
Some operators already offer flat rate packages for several countries. E.g. my operator the Finnish-Swedish TeliaSonera offers me unlimited data, calls and sms for Fennoscandia (fi, se, dk, no) and the Baltic countries.
Disagree about the "should". Why would we not want to survive indefinitely? And when it comes to species, humans are clear outliers. I'm not sure how well one can extrapolate human future from what happened to the dinosaurs.
The fluffy box thrown around in the audience is a microphone called Catchbox, developed by students at Aalto University. http://thecatchbox.com/
We had some problems with the Catchbox during the beginning of the talk (the sound didn't get through to the live stream) but it worked surprisingly well after that. I could hear myself chuckle when holding the box as I listened to the video afterwards.
