a) the more we venture further into the unknown the more cautious we can get, and we should get. Even, if you say, that's not the way it is. It might be better. Not saying it IS better, but might be...

b) I just proven my point. Humans are ignorant bastards. You can't deny the fact that this will create massive problems in society.

c) Yeah, but during that time, wars will erupt and kill millions who already could have been saved. Lose money, lose the greed out of humanity and everything bad. Then we can talk about free immortality for everyone.

d) We are soooo far away from proper interstellar travel with technology, that putting a handful of people in a tube and sending them far away while the rest of us dies here whilst they're travelling. I still think we will find answers regarding how fast can we travel. What about huge colonisation ships, on which people can live for generations? The great filters are mostly speculations. Some stuff we look back on and go, 'Hey that was a filter. Thank god we survived it!'. And there are always more answers for one problem. Oh and you forget there might be another issue. Living in space during the venture. That is hard for the human body, even if you live forever. So unless you change into robot, which is not as good, because solar winds, radiation, etc... What if we let humans evolve into space life?

e) Maybe, maybe not...

f) That is silly again. Over the years much has changed in our body. Just go and have a look at old castles, houses in Europe. A few hundreds of years ago the people were much shorter. Our body structure changes and adapts, but so does everything else in us. We are still evolving as we speak. Maybe the environment for the dinos was a bit harsh. Humans couldn't have evolved in that. Not to mention live. That's why being a dino was they way to go. A lot of people agree that it is a freak accident, that we have such a calm few thousand years without any huge issues in climate and vegetation. Now it is better, because we can shape our surrounding. Of course this spirals down into us killing everything that moves and has meat, fur, tusks, whatever... Mother nature is not stupid, there was a reason why the dinos couldn't evolve but still they were the dominant species. And it would be foolish to say they didn't. Not every dino lived in the same prehistoric age at once. They evolved from each other. Only an alternative history would know what would have happened, if dinos remain here.

g) Ok, than why do we have organisms which live basically forever and we're not one of them? And why aren't these immortal creatures not the true rulers of Earth by now? I'm not a biologist, but I do see a relation here between the necessity of death and evolution. As we mix our DNA we create better and better offspring. Immortality kills the need for offspring.

This is not off-topic. It would have been off-topic for me to comment: ' Hey what about vanilla flavoured ice-cream? How the hell they do it!?'

Anyway I enjoy this argument. It wont hurt you get a bit out of your comfort zone. Sorry if I annoyed you in any way.

Oh and I would love to have a cyber-brain as they have it in the Ghost In The Shell world. If my body dies I could still transfer my brain into something else. Like a big robot or something, or just a jar. Maybe creating this kind of hybrid solution would be the answer. If we can continue with our current body to evolve, but have our brain picked out if we want to... Maybe that would help. And the human robot doesn't need fixing, it is good as it is and what it will evolve into. Stepping outside of it might be a better solution then fixing.
