Nanotechnology could make men immortal by 2040
Ray Kurzweil, author of the books The Age of Spiritual Machines and The Singularity is Near: When Humans Transcend Biology, says that nanobots will soon end cancer, store backups of our memory and slow down aging.
In 30 or 40 years, we will have microscopic machines that will travel through our body, repairing cells and organs, to end disease. Nanotechnology will also be used to store our memories and personalities.
In an interview with writer and futurist Ray Kurzweil at Computerworld, he claimed that anyone alive by 2040 or 2050 could be close to immortality. The rapid advance of nanotechnology means that the human condition will evolve towards a human-machine collaboration, as nanobots will flow through our bloodstream and will one day even replace biological blood.
This may sound like a science fiction movie, but Kurzweil, a member of the Inventor's Hall of Fame and recipient of the National Medal of Technology, says the research being done Performing today will lead to a time when the combination of nanotechnology and biotechnology will end cancer, Alzheimer's disease, obesity, and diabetes.
By then, humans will have increased their natural cognitive ability as well, and their lives will have lengthened by a few years, Kurzweil added.
Of course, people can still be struck by lightning or hit by a bus, but much more trauma damage can be repaired. If nanotubes swim through our bloodstream or even replace biological blood, wounds could heal almost immediately. It would be possible to rebuild the limbs and access the backup copies of our memories and personality after suffering damage from head trauma.
Currently, MIT investors are already using nanoparticles to target killer genes that fight cancer in its later stages. The university reported last month that nanotechnology-based treatment eliminated ovarian cancer, considered one of the deadliest, in mice.
And earlier this year, scientists at the University of London claimed to have used nanotechnology to kill cancer cells in mice with genes "that kill tumors," giving new hope to patients with inoperable tumors. So far, tests have shown that this new technique leaves healthy cells intact.
With all these jobs underway, Kurzweil says that by 2024 we will add one year to our life expectancy for every year that passes, and in about 35-40 years, we will be basically immortal.
According to him, adding these microscopic machines to our bodies will not make us less human. "It is in the nature of human beings to change who we are," says Kurzweil.
But no that doesn't mean that there aren't parts of this future that you don't care about. With nanotechnology as advanced as the one described above, not only will come benefits, but also dangers.
Nanobots, Kurzweil explained, will be able to duplicate themselves and engineers will have to stop this duplication. "It could be that a nanobot with the ability to duplicate itself creates copies of itself ... and finally, after 90 duplications, it could devour the body in which it is found or those of all humans if it becomes a non-biological plague," added Kurzweil . "Technology is not a utopia, but a double-edged sword and has always been since we first discovered fire."
