This might not be the most productive comment, I'll admit, but I genuinely feel this way about most interviews/blog posts from execs/leaders/etc. in the startup/tech space.

have you read his blogs? he has always been like this.

When executives are in broadcast mode, their delivery is tweaked for emotional impact on the listeners. They try to inspire, motivate and get their points across using concepts well understood by their audience.

If a leader’s speech is coming off as too corporate and hand-wavy, they have failed to read their audience and adapt their messaging to its level.

And very confidently too. Similar to his product.
