As far as offense goes: I am not offended that you think death is inevitable. I am offended that you keep posting to say that death is inevitable and therefore I should let myself, my loved ones and everyone I've ever known die without doing anything about it. Because you keep posting statements to the effect that me dying is natural and right, me avoiding death is unnatural and wrong, I am a bad person for wanting to not die, and that even if I did live into the future, people there wouldn't want me or anyone like me to continue existing. Maybe that's not what you meant, but it is what you said.
Yeah, I'm sorta getting this vibe as well. Personally I haven't seen any reasons you've put forth that have been valid reasons for why everyone is going to die other than "because that's always happened in the past". I mean sure, I know that I personally might not make the curve point where we are on average extending your life by more than one second per second, but I can see the point where the curve exists in the future, and I'm not seeing anything out there that would impede it from eventually coming to pass in the future.
And even if you want to play the long game I'd be just as willing to argue that there will be some day, billions of years from now, when we crack the universe to save it from its own end. When we jump from this universe to the next one to dodge the universe's end, or drain energy from the infinite area beyond what we can see to power the little that we can, or hell, maybe we all evacuate the future and take refuge in the past through time machines. There are plenty of ways that aren't prohibited by (current) physics to essentially "turn back the clock" on the universe's lifespan and buy ourselves even more time to work on solving the problem of the universe's eventual demise.
And the reason I can say these things is because
I've done the research. I've read papers on cryogenics and looked into the logistics of it, I've spoken about medical prosthetics with college professors and PHD's in that field, I've listened to lectures on what we might hypothetically do to stop the end of the universe, and I've attempted to stay up to date on a large number of current neuroscience and computer projects that would be involved in a brain modeling and uploading project. I'm not saying these things because of some misplaced faith in future technology as some sort of "god" or something, but because
I know what the technology can do already, and I've seen the developments and applications researchers are working on for the future, and anyone can see the combined implications of those technologies when they've accessed all the data that I have. The fact of the matter is that there are scientists working right now, as we speak, on technologies that, working together, could end death.
