Just say we exhume, for example Bach, from his grave and extract some DNA from his remains.
We then clone him, implant him in a woman, allow him to be born and bob's your uncle. Another, identical version of the great JSB.
We have the technology. Should we do it?
Is it even ethical?
How would Bach feel about being brought back?
What would you do? Treat it as some sort of amazing social experient? Put him to work composing more music? Send him out on stadium tours? Make a reality TV show about him growing up called, "Bach's Back"?
Just think what the world could learn, could gain, by bringing back Bach. But what's the cost? What rights and responsibilities do we have towards him?
If you're opposed to cloning, would the benefits outweigh the constraints?
