When I was a young boy I used to build robots in the basement out of things I thought looked roboty. Old vacuum cleaners, plastic boxes, frayed wires, wheels, eyes, hearts. While I was constructing my robots the thought never crossed my mind that they wouldn't come to life.
They never came to life.
Do we do things knowing that there is no purpose for doing it? Are we certain that our endeavors will be fruitful? Have you heard that no one lives forever?
And yet we still fall in love and make promises and look forward. We thumb our noses at finality. We challenge nature's rules. We press our luck that maybe, just maybe our robots will come to life.
