Why you should be reading more of Ben Collins-Sussman:
I usually find it easier to encode my home videos into the immutable portion of some custom-fabricated DNA, which I then implant into bacteria and launch into the stars. I figure that in billions of years, they may evolve into sentient life forms, examine their DNA, decipher the codec, then watch my children play ball. Gotta make the important memories last.
