100 years from now, Bieber & Zuckerberg will be immortalized in the annals of history, and deservingly so. Life is so fast paced and information travels faster than the speed of light that it is all a matter of timing to become ludicrously successful. I think in our current age, we only have 30 years to make it (from birth). Beyond that, if you manage some form of success, you belong to the anomalous faceless multitude flock of swans. Bieber & Zuckerberg are the black swan. Bieber, being accidently thrust in to the sky, and Zuckerberg having more control in his trajectory towards the heavens.
