It's naive to think the word's richest man and most important defense contractor can simply put out publicly everything he knows and thinks... especially on something like Bitcoin that needs to look completely organic to get global buy-in.

If you had a chorus of the most powerful and influential people in the world say Bitcoin is the next world reserve currency and they'ere all in 2010, it'd never have been adopted. People want to be first then have the powerful confirm their bias, not follow them.
