Oh yes that I could see happening, definitely, but to attach a head to a completely foreign body is ridiculous, it’s Nazi fantasy stuff.
But growing organs from someones cells is completely possible, it would be incredible if you needed a new heart or kidney they could grow you one and it would extend life a great deal. But I think there is a limit to how old someone can get before the brain basically turns into jelly. They can replace every organ but they can’t replace the brain otherwise it wouldn’t be you anymore. Plus why are they looking to extend peoples lives anyway? They would have to deal with the ever expanding world population at the same time. If they are going to extend peoples lives, then that is going to be added pressure on a world population that is adding a billion people every 10 years and that time frame is speeding up. 2000 years ago the entire world population was less than the current population of the US alone and it took 1,800 years just to reach a billion. Today we reach a billion in 10 years. Soon it will be every 5. This is why all these 3rd world nations are spilling over into developed countries, why housing costs have quadrupled in the past 20 years, why traffic is getting more and more congested, why a college education isn’t worth squat today, and why rural areas are becoming more and more developed. I mean what is the limit? Until every last bit of land is like a city with people all squashed in buildings living on top of each other? Right now there are more homeless people living in New York city that there ever was during the Great Depression. I find that absolutely mind blowing, but that is a direct result of population expansion. It will get to a point where the streets will be crowded with the homeless, when having a house or apartment will be as rare as winning the lottery because the cost will be so insanely expensive, that’s if money even has any value in the future. Food and water will probably replace it. But we keep getting these breeding cows who got to have litters of kids and everyone keeps saying “Oh isn’t that so lovely that she has 20 kids” No it’s not, that is nothing but a pig.
” Plus why are they looking to extend peoples lives anyway?”
Perhaps you are missing the point..
There is no concern about overpopulation or burdens on society. Some people would pay all they own for the dream of hanging around longer. And some of those people have billions to spend. Wink, wink. It is about power. Think of a Hillary Clinton, ruling us for generation after generation.
