You cannot copy "all" of the information stored in the human body. Briefly, this happens because the physical limitations of information storage require cooling (Landauer's principle) which requires kT×log(2) energy per bit, or about 2.5 zJ at room temperature. The brain's memory capacity is about 2.5 * 10^15 bytes ( https://www.scientificamerican.com/article/what-is-the-memor... ), but the amount of information whic…
Copying a disk does in no way require simulating each atom of the disk, though? • We can already clone mammalian bodies. • I'll assume that "growing" an adult human body, with a "blank" or "default" brain, isn't too inconceivable. • Your real, natural brain can access the information within itself. • At the moment of "copying", we figure some way to biologically link the two brains together, and write some biological…
I invent a machine that "scans" your body in such a way that I'm able to create a perfect replica of the state your body was in, nearly to the atom. Molecule, by molecule, the machine can rebuild your body, within a near infinitesimal margin of error.
I put you inside this machine, and scan your replica file, and then I save it to a massive storage device, and, when called upon I can rebuild that version of you whenever I want.
Now, after being successfully scanned, you exit the device. I blow your head off with a shotgun, and your headless corpse slumps on the floor. No witnesses.
Do you really think you'll come back to life, if I print out your replica from the file?
