Why do we do what we do?
For some it’s ego; sometimes people really seem to care how the world views them. Other times people seem to act out of necessity, whether to keep themselves sane or just to pay the rent. The truth is that the pretext is arbitrary, because after we're gone, what we've created will be all that remains, for a time. Given enough time, even that will become mere breadcrumbs to lead future generations on some wild goose-chase as to why things went down the way they did.
One fact is certain:
We create because we can, sing while you may.
