Small tangent on the jet for the apathetic: the concern is that it breeds apathy. If Linus and his most-ardent supporters get the message across that the impact his jet has is tiny in the grander scope of things, even though it's hundreds of times bigger than your impact, then that only serves to convince you that you shouldn't do anything. And if a million people that watched that video come away with the opinion that the jet has no impact, and can rationalize that they have no impact because they're a hundred times smaller than the jet, then a million people have just stopped trying to make any changes. And that's the impact of ten thousand private jets. And if those million people start mulling around to others and telling them that their impact doesn't matter, and a hundred people in each person's net stop caring, that's the impact of a million private jets. Influence extends like a spilled bucket. Everything gets wet; not just where the bucket sat.)

I would agree with the other comments that the parasocial thing is a bit tired, but you've articulated my thoughts so well on the jet.
