Watched the whole thing, even the (mostly idiotic) questions at the end. It's like getting out of the office, climbing up a lovely mountain, breathing fresh air and looking up at the stars with no light pollution... it is refreshing, beautiful, and reminds you that the world is a fantastic place full of amazing people. This is the America I live in, and I love. And Elon Musk is simply the most awkward presenter that has ever lived. But he says such beautiful things, I forgive him. Every time.
I didn't make it past the second question in the Q&A... Did I missing anything interesting?
Yes, there were two actual scientists that asked actual questions, but they didn't think their questions through, and therefore the answers didn't really add anything substantive to what Elon had already said. You can skip the Q&A. It'll give you more faith in humanity. :-)
