He is just like you and me (nerds) doing the best he can at a role he isn't very suited for (public speaking). When you consider this and he still doesn't try and palm this stuff off I think he is doing great.
He sounds genuine, and he probably is, but he chose to keep it that way, he is not a poor nerd crumbling under pressure.
Think of it: he has over 20 year experience as an entrepreneur. Actually his whole career after school was being a business man, with the majority of it in high level position and with considerable success. During his career he had and still has to talk and negotiate with Heads of States, Nasa Scientists and Astronauts, Banks, other CEO of the most important companies in the world ( his peers ), ...
He chose to do the unveiling, he has the confidence to do that. If he thought he was not up to it or that his style was letting him down, he could have chosen any other unveiling strategy.
I think it's because he knows the presentation in and of itself is unimportant vs the takeaways delivered, so he doesn't bother wasting time on it specifically since it has low ROI given his speaking capabilities. And I suspect he dislikes acting/faking, so he wouldn't use precise scripts anyway.
