I'm surprised they didn't just have them very old. They would have been roughly 120 years old when the ship arrived. I would expect that with their modern science that would be very normal for people to live that long. They expect people of our generation to live that long,or close to it.
That's just pure sci-fi speculation on your side. There's no real reason to believe life expectancy will go anywhere over 80-90 in the near future (with most of them still being walking corpses past the age of 80). You say "There is an exponentially increasing history to life expectancy" but what is it based on? Purely on the increase in the quality of life of an average person plus the availability of medical care which has pretty much reached its maximum. The only way to further increase the human lifespan would be some big scientific breakthrough which may or may not happen in the near future.
This subject reminds me of the historic increase in average IQ - on the first look, an uneducated person might think people were all idiots 100 years ago and that in the year 2100 average person will be a genius. But the catch is again in the cause of IQ growth, which isn't some predictable natural growth but instead the increase in quality of life which helped more and more people fulfill their genetic potential. And once everyone has the conditions to fulfill their potential, the curve flatlines.
Why in the world would you think medical care has reached it's maximum? Unless you think science and technology are going to quit advancing for some reason, why can easily assume those technologies will continue to extend life, as they have been.
You misunderstood. I said availability of medical care and quality of life. I acknowledge that science will probably keep advancing, but can we say for sure that technologies with the potential to extend life that much will be available in the near future? It may be 50 years from now, but it may take centuries before we effectively stop or at least slow down enough the process of aging. And I repeat, THE PROCESS OF AGING is what it's all about. Stuff like organ transplant and limited gene editing and therapy can only get you so far. You can't transplant brain and even if you could, nobody yet has any idea on how to stop the aging of the brain so in the end you're still left with 80+ year olds as senile as their ancestors in ancient Greece who were (un)fortunate enough to reach the same age.
Once we can pinpoint and repair individual cells, we will be almost immortal. I took the med Bay in this movie as something similar to this. Even mental deterioration would be something we could fix at that point. We need to survive as a species long enough for that to happen.
No because in the Bible it says God set man’s age limit at 120 years after the Great Flood, so no matter how many technological advances we make, that’s as high as we can go.
