> > You do know that every culture, since the beginning of time, has thought that they would live to be immortal in their lifetime. What makes you think you're different? Sure, you might have a better chance, but it's still a slim chance.

> A slim chance is infinitely better than no chance at all. How many cultures had even the remotest chance of actually doing something about it?

None, and we're no different. Why would we be?

> And no, I'm not certain it'll happen in my lifetime. I'd say that I'd be sad and disappointed if that didn't happen,

Well, no. You'll be dead. Dead people aren't disappointed.

> I also consider it worth advocating, to encourage others to push for the same goal, or at the very least discourage others from perpetuating arguments that shut down such efforts.

I don't agree that it's worth advocating. Yes, curing diseases and other such things is a worthwhile goal. But the goal of living forever is just selfish. Note that children couldn't exist in a world where people live forever (otherwise we'd run out of resources even faster than we are now).

> > Actually living forever would be a greater hell than anything I can imagine.

> Then don't. But I'd suggest trying it first, or significantly expanding your imagination.

I have a very vivid imagination. That's how I came to that conclusion. Also, how can I "try it"?

> > After the first few hundred years, when you realise that it's never going to end, after you've read every book and done all you've wanted to do, what then?

> With all the imagination you can bring to bear, and a universe full of possibilities, you can only think of a few hundred years worth of things to do before you'd not only get bored but get so bored you'd long for death?

Yes. Why do you think any differently? Evolution has placed a cap on our lifespan, because living longer than that wasn't better for our species. Have you considered that? Why do you think we'd be able to contribute anything meaningful to the world after we are 80 years old? Aside from helping younger generations (which don't exist in your world), we have nothing left to do.

More than 98% of people who ever lived are dead. It's incredibly arrogant (and akin to a tantruming child) to assume that you will survive.

> To give even a minimal lower bound based on your own comment, books and stories are already being written today faster than they can be read. And that's only one of myriad possibilities. A few minutes imagination can easily produce far more interesting ones.

I'm a scientist (as well as programmer). So I can imagine spending several hundred years trying to solve all of the scientific problems that exist. But after a few hundred years, I'll definitely get bored of that. So, I'll have to move on to something else.

> Do you currently get bored with life and want it to end? If not, then why do you expect that to change in only a few hundred years?

No. But that doesn't mean I won't get bored of it eventually. Not to mention that I can see myself being bored with <things I'm interested in now>, and no doubt I'll eventually get bored of all of the things that make me a productive member of society. At that point, I'm a drain on the world's resources. What benefit is there to keeping me alive?
