Would people even remember me if I disappear from the face of the planet?

Dude, our world as we know it continues on. For a long, long time.
We will be forgotten and in 200 years no one will even know who you were or what you did.
Life's too short to sweat the little things, and really we are little things on the grand scale of what we know as the Universe.
Come sit down have some ice cream, my treat!
