Most of us have pondered living forever. But what are the ramifications, and is it even possible? According to scientist and author Ray Kurzweil, it’s possible and we will need to ask ourselves these big questions in the next 20 years. The key to immortality may lie in nanobots replacing our blood cells.

This might appear not only far-fetched but also a bit spooky. Kurzweil is very enthusiastic about these ideas and so are some pretty well known people. Bill Clinton and Bill Gates are big advocates of Kurzweil’s ideas.

Rise of the nanobots?

Regardless of how “out-there” Kurzweil’s ideas are, they may be a very real possibility. In about 20 years, scientists believe they’ll have found a way to halt and reverse the aging process. Kurzweil then feels that nanotechnology will come into play, replacing human blood cells, and carrying out the work much more efficiently.

Exponential technology

Kurzweil bases his predictions on the undeniable fact that technology is evolving at an exponential rate. Taking this into consideration, immortality may be just a few more technological leaps away.

The bigger questions that arise out of this debate are: Should humans live forever? If we do, will the earth become overpopulated? Will this ruin our natural resources? Who’ll get to live forever? These are huge questions, which, if Kurzweil’s predictions come true, we will soon be facing.
