A smartphone. So that when, in 50 years from now when we live on harsh, unforgiving wastelands filled with no trees and toxic waste that has turned into sentient lava…when we’ll be deciding who has the biggest penis through rudimentary bladed weapon combat in arenas filled with mechanical guillotines and hungry polar pigs…someone can find the smartphone while digging graves for the thousands who have been bested…and then they can worship it as a god, then eventually study it and use its technology to bring man back to an age of prosperity and intelligentnesseses, that which SHALL BE GREATER THAN NOW.
THAT WAY I WILL BE THE ANGEL WHO FROM THE DUST, RISES MANKIND TO SALVATION, AWAY FROM ITS BRUTAL STAGNATION AND LACK OF EMPATHY. But fuck that, it would be pretty cool if we just acted like Vikings all the time.
Anyways that wouldn’t work out, because in such a post apocalyptic scenario that I think came from Heavy Metal, people wouldn’t bury their dead. They’d either fuck them, eat them, impale them on pikes or all three. Most likely, all three.
But yeah, to answer the question, a smartphone. And possibly, some Harry Potter books. In ebook form, f’course.
