Artificial hearts, kidneys, livers, stomachs, ears, and eyes, are all being seriously manufactured and positioned by medical scientists. This has prompted some to assert that immortality will be available to humans by the end of the 21st century – at least to those who can afford it. Yet other thinkers can see that the affluent ‘immortals’ are likely to resemble robots, as its unlikely for a human brain, and thus memory, to be manufactured. And what about those who can’t afford to replace worn out body parts? Something to think about.
