i want to be immortal because i have a god complex and 10,000 years from now i want to rule the universe... lolz. not really, but i do have this fear that by the time i die i wont be satisfied with how much i know about the universe. imagine if a caveman could experience todays technology...... and then communicate with us about the days from his early life. Life is ever changing and if you take our timeline and reel it back in 200 year segments, and use that growth to predict the amount of future changes, keeping in mind the massive leaps in science and the actual acceleration of the speed of our discovery...... I have a feeling if we dont all kill eachother or get destroyed by a natural disaster.. the future will always be a very different place.
