Nothing that exists within the expanding Me is worth remembering or preservation. All intelligent life across the cosmos share the same useless thought; "My World Will Always Exist". One day, everything will be destroyed. It doesn't matter if it's within your lifetime or the lifetime of your 10th generation grandchild. Everything you've ever created, imagined, built, manufactured etc. All the interpreted information cataloged and deciphered by the smartest of your species. Gone. Existence is nothing, the choices you make and the experiences you obtain from those choices, again amount to nothing.
This would be the conclusion area where i would say something like "Grow up and observe the bigger picture" or "Stop living in your childish fantasy worlds" but in a universe where nothing matters and everything eventually becomes nothing; Do whatever the fuck you want to do. If it makes others miserable, why should you care? You will eventually be nothing.
