I think you have to distinguish between nay-saying as a stylistic means and arguing with his point. I think there is a valid philosophical point to be made that young entrepreneurs are not daring enough. Aside from the fact that it's really, really hard not to settle for "easy" execution, society would probably indeed be better off if people dared to go for more daunting tasks. I guess you can say: If you want to glorify some people - like BW does -, select mostly those who try (and most certainly will fail in doing so) the truly groundbreaking stuff. Those are the ones that society needs to succeed. But it's all philosophical.
