Steve Jobs presentation skills, ironically, leverage little in the way of technology, and everything in the way of presence.

What's your issue with the Outliers 10K hours expert thesis? Do you have any sources that indicate a significant number of individuals with a baseline skill of ability in a particular ability, who also put in 10,000 hours of _focused_ practice _haven't_ established "expertise?"

That particular thesis of Outliers very, very strongly resonated with me.

I haven't read the book, but it just doesn't seem very plausible that one needs about the same number of practice hours to become an expert at any of several hard but unrelated skills.

This presentation goes a bit beyond that and suggests that giving presentations is like brain surgery.

The actual research articles on the subject (Ericsson and others) are really interesting, though. It's not about a magic number, but the fact that deliberate practice has a marked effect on the level of expertise.
