I'll avoid naming specific names here so that the reader can (probably rightly) project this onto whoever they want instead of rejecting it for naming their idol but... This is the problem I have with listening to the public "opinions" of major CEOs in general:

Their statements are usually made in service of a goal, not earnestly-held good-faith opinions. Even if someone is "very intelligent", what makes you think they are giving you access to the fruit of that intelligence? How do you know they aren't using their intelligence to try and manifest an outcome that would be beneficial to themselves, completely divorced from what anyone with their level of access to information could possibly believe (much less someone intelligent)? Sure, they'll tell you some truth if they happen to believe that doing that will reward them. But they'll also tell you that they're deeply committed to your local city when they have a meeting to discuss tax incentives for moving their HQ later that same day or that their plant has a sterling safety record while deliberately burying records of payouts for injuries. The only real difference between this and someone like Holmes is that they have a better level of skill in forecasting consequences.

What this ultimately means is: There is often little value in listening because you end up having to estimate the truth from less-manipulative sources yourself. And if you're going to spend the time and energy to do that anyway, you can skip straight to this step.
