Endless possibilities. Or not. With immortality comes infinite ambitions, visions, and "life dreams." But would people really have the urgency and drive to pursue them because they would have all the time in the world? Literally. Maybe there would be no concept of procrastination because you can always say "I can always do it another day" and there is no counter-concept to this. It would be the only norm.
Less meaning, perhaps. One of the things that make life (as we know it today, at least) meaningful is its finitude and how this finitude drives people to spend most of their time on things that are their passion or would somehow make a difference in this world. If you think of the movie The Bucket List, they wouldn't have had the motivation do to all those things if they were not dying. I wonder if there would be such things as life crises (quarter-life, mid-life). Would people even stop to think what their purpose on this earth is? Would people even ask existential questions?
Would immortality bring new emotions to humans? Or would certain emotions be inexistent because of it? One emotion that I never want to feel is regret because I know that I can never go back to the past time and undo things. I also don't know if I'll ever have the chance to make it up in the future. With immortality, people can still be certain that their paths will cross in the future because there will always be one.
What would history be like? If people lived forever, I would have the chance to meet great people in history like Plato, Socrates, Shakespeare, and Einstein. But what would people's concept of history be if everyone could live forever?
Maybe murder would be at stellar rates. Going back to my brother's instinctive answer of overpopulation, what if everyone would be so competitive of space that people would just start killing each other?
We won't be the humans we are (physically) today. The murder possibility sparked another thought in my head. If murder was the only way to go and people can't die of diseases or old age, how would we define "healthy"? Maybe our body systems would be totally different because we won't have any use of our immune system. Cell regeneration would be limitless. There would be no doctors on earth. We'd be physically invincible. And maybe we would all take this for granted.
I'm usually the optimist, but I feel that this is one of my most pessimistic thoughts to date. Maybe because I believe in the concept of the Yin-Yang. For something to exist and be valued, its opposite must exist as well. What would light be without darkness? What would life be without death?
