How Long Should We Live?

So I'm having some trouble finding a link related to this topic. I'll keep looking. I really wanted to talk about it anyway. Technology is already helping us live longer lives. People live much longer now then they use to live. What if in the future we can live as long as we want? How long should we live? Is it ethically responsible to live as long as you want or should you make room for someone else? The longer people live the more of a population issue we are likely to have.

Addition since I first wrote this. I have found a web site that somewhat deals with this topic.

I, Robot

I love this movie! And I love the ideas presented in it. Basically, it is a movie set in the near future where humans have robots as their servants. One robot is created with true AI, which sets off a sequence of events that seem to lead toward some kind of robot up rising and self-actualization. (However, the robot up rising and self-actualization is not part of the movie, it is only suggested.)

If in the future we succeed at true AI and pretty much create life then well, what then? Are we going to respect that life? Will the general population see this life as equal? Also, The Three Laws is an interesting concept. Should we program AI with laws that are designed to protect humans? What about robot freedom? Is this a real concern or is true AI unrealistic?

Timeline

Timeline is a book written by Michael Crichton. New technology and science always provokes the question: Will this power be used for good or evil? Sometimes it isn't even a matter of intent. Sometimes people just don't understand the power they have and they accidentally ruin things. As you might have guessed this is a book about time travel. Some of the characters are out for selfish means while others are just trying to save a friend. However, the whole story and situation makes me wonder: If we had the power to go back in time, should we? Could we really understand the situation clearly enough to not mess things up? And of course there would be people whom would want to change history to suit their desires. Is it a power best left alone?
