For modern technology, it seems like even the sky would not be a limit. It has grown so much that numerous movements have emerged out of it that are dedicated to shaping, thinking and guiding possible dimensions that technological trends might take. Nanotechnology manipulates atom, molecular and supra molecular material at the scale of 1-100 nanometers (a nanometer being a billionth of a meter) to make useful products.
Transhumanism is an international intellectual movement espoused by highly idealistic people who believe that human understanding can surpass natural limitations. Enhancing human capacities, such as lifespan, intellect, strength, speed and metabolism is imperative. Moreover, recent Nano-technological ventures to prolong life, improve biological and intellectual capabilities have increased optimism.
Transhumanism believes in a future where through nanotechnology, human existence will be transformed, suffering and death will ceased, and cryonic corpses will be brought to life. The new human race will be immortal, free from hunger and be able to upload the brain and consciousness of a dying person into an ultra-fast nanocomputer to escape death and continue a virtual existence. This immortal species will be characterized by immense strength and incredible intelligence that will make them super intelligent and also super human.
With their enhanced capacities, they will develop nanorobots to perform human tasks, monitor the human body, heal ailments and enhance brains that are uploaded to a computer with super intelligence. This will help humans evolve to post humans. The post humans will be a blend of human matter fused into Nano-computers and will be termed virtual humans.
Such far-reaching implications with the human engineered evolution as opposed to natural selection will generate debate. There are concerns that modifying emotions, bodies or chemical balances that have evolved though millions of years may be counterproductive.
Perhaps the best approach would be to allow innovations to happen but develop as per national and international regulations to guide these new technologies.
