> It's mandatory to use the pause key to understand the full details

I was going to say I disagreed but the rest of your comment reminded me that I've accumulated a lot of domain-specific knowledge.

What I meant is that at points he skips past slides so quick even very fast readers can't absorb every bullet point. I read at ~2-3x the average speed, have lots of domain knowledge and couldn't read fast enough to get every word on every slide. So the pause key is very useful for that even if you know what's coming.
