“More and more, it seems, the priorities of these institutions do not align with those of the people they serve. Remember when Facebook toggled the digital levers in its social network to run massive psychology experiments on its users? When confronted with an intractable problem, we’ve settled for the least egregious option by placing responsibility for our digital data in as few hands as possible. Because, really, the only thing sillier than trusting some central authority with our most precious digital records would be trusting a bunch of strangers with them. And yet, this is precisely what Bitcoin achieves: a public database that everyone can see, anyone can add to, and no one can destroy.”
