I had been looking forward to watching the EY's presentation, and was bitterly disappointed.

On stage he looks like a novice speaker, committing a slew of rookie mistakes: most of the jokes fall flat, the slides are uninformative for anyone who is not already an expert in the area (and useless for anyone who is), he constantly complains about time constraints (did they shorten his time unexpectedly at the last moment?), he does not leave time for a conclusion, he talks at a level likely inappropriate for the audience, he flashes a score of slides toward the end to show that he's done more work than he was able to present...

Now contrast this with the presentation that immediately follows, by a seasoned pro, Max Tegmark, who knows how to be engaging and hold the audience's attention and how to get his point across, whose slides are well thought out and whose jokes elicit the intended reaction.

I am loath to give advice to a person who is orders of magnitude smarter than I am, but, were it anyone else, I would recommend a basic presentation-giving training, such as the one I took ages ago.

EDIT: That course is also where I first learned how to structure oral and written presentations.
