Warhol said, “In the future, everyone will be world-famous for 15 minutes.” He was onto something. The nature of fame has changed a lot since then, because the nature of the media has changed. Warhol was working in an age of mass media—as is so well captured in his art. We now live in the age of democratized media and democratized media have democratized fame. The users of these democratized media, like Instagram, live partly in a virtual copy of the world. As in the work of Warhol, fame generates icons, and these icons take on a life of their own. In Dead Celebrities, Living Icons, cultural critic John David Ebert suggests that this is the very transformation Warhol anticipated:

Indeed, looking back over the various biographies of the celebrities we have covered in this book, it becomes clear that they represent the pioneers, as it were, of the current mass exodus into hyperreality...

Additionally, space was rightly perceived as a realm with great power for war and peace. The conquest of space as satellites were pushed into orbit around the planet was the source of great anxiety. Those countries that could do this first would gain the higher ground...

Nowadays everything seems replaceable. Discussion of the successors to credit cards and gas-powered cars is common in a way that discussion of those to paper currency and oil lamps never was. The status quo is so quickly shifting that any everyday annoyance is seen as a gap to be quickly filled, an opportunity waiting for any company that will seize it.

Of course, however, not everyone who notices such an annoyance will jump to form a company around it. Most people never really pursue these ideas; they acknowledge them and patiently await their solution by someone else. Those who do attempt a solution will only do so up to a certain cost. It’s human nature to be at least somewhat risk averse. Your valuation of cost, however, is not strictly a function of missed opportunities or necessary resources; this blow can often be softened when a project is compatible with your identity and...
