Don't we actually need doctors, lawyers, researchers, critics, engineers? I realise he wasn't saying that everyone should become an entrepreneur like he is, but it's worth saying that grades are important.

Agreed, this is advice that's steeped in Silicon Valley culture. Not everyone has the same resources, nor does everyone need to be some sort of entrepreneur.

Rather than add to the noise by podcasting/blogging, better advice would be to connect with most talented people who do what you do and learn from them. If you find that you have a platform and something to say, then do so.
