There's absolutely nothing wrong with what I've proposed.
Typically only people that believe in a soul or that humans "should die" take issue.
Neither of these is correct in my world view. I can understand the religious perspective, but the romantic idea that limited live spans are good is incredibly twisted.
I think people should be immortal, but that's just not feasible. The next best thing is using all of the tools around us to extend our lives as much as possible.
I'm tired of biology being so punch-card slow while the compiler is literally staring us in the face. The human is the perfect model organism for everything we want to accomplish, and I've shown that we can ethically build upon it as a platform without harming anyone. Moreover, we can farm it. Never deal with blood or organ shortages, end immunosuppressants for many people, and potentially perform purely regenerative surgeries.
A human grown in a lab without a brain is a plant. Dogs, apes, and octopuses are more human than that. Before you fight me, go take on the many acts of animal cruelty in the world.
The people that would hold this back are Luddites.
This is a faster path to curing cancer. All fifty thousand types of it.
edit: Down voters, why not argue your point instead? Because from my perspective your views are a dated death wish.
