How are they going to do the whole benefit in 2 hours?

This may be the wrong subreddit but this post is about the Complexly benefit.

They have so many speakers and the game that hank mentioned and the whole thing says (as far as I understand) that it is from 7pm-9pm.

Is it just rapid fire quick talks for 2 hours? Is it all one talk with different speakers? Am I misunderstanding something or does it feel like this isn't possible or is each contributor doing way less than I'm imagining
