He calms down when he starts talking about risk and it being the anniversary of a launch.
edit: Good and fun presentation regardless!
edit2: Thoughts:
- Maybe he feels in over his head. The timing when he relaxed seemed to coincide with talking about a previous experience that might have felt overwhelming at the time but paid off.
- Maybe he typically takes beta blockers or something for speeches and take them until late this time (the talk did start late)
- Maybe it's just random.
Any spacex watchers have thoughts on cause?
edit3: Definitely not a diss. Love Elon/SpaceX/the vision.
