In the past I have talked on the 'future human' in terms of the homo gestalt or homo noeticus which I feel are more spiritually aware understandings of how the human species may evolve into a next stage, in terms of awareness, synergy, collective consciousness, and higher vibrational nervous systems.
Now, from the Tech-pack comes a future model that is more in keeping with the Technological Singularity model - in this recent article by tech-pioneer Ray Kurzweil titled 'HUMAN BODY VERSION 2.0' he writes that:
In the coming decades, a radical upgrading of our body's physical and mental systems, already underway, will use nanobots to augment and ultimately replace our organs. We already know how to prevent most degenerative disease through nutrition and supplementation; this will be a bridge to the emerging biotechnology revolution, which in turn will be a bridge to the nanotechnology revolution. By 2030, reverse-engineering of the human brain will have been completed and nonbiological intelligence will merge with our biological brains.
Sex has already been largely separated from its biological function. For the most part, we engage in sexual activity for intimate communication and sensual pleasure, not reproduction. Conversely, we have multiple methodologies for creating babies without physical sex, albeit most reproduction still does derive from the sex act. Although not condoned by all sectors of society, this disentanglement of sex from its biological function has been readily, even eagerly, adopted by the mainstream.
So why don’t we provide the same extrication of purpose from biology for another activity that also provides both social intimacy and sensual pleasure, namely eating? We have crude ways of doing this today. Starch blockers, such as Bayer’s Precose, partially prevent absorption of complex carbohydrates; fat blockers, such as Chitosan, bind to fat molecules, causing them to pass through the digestive tract; and sugar substitutes, such as Sucralose and Stevia, provide sweetness without calories. There are limitations and problems with each of these contemporary technologies, but a more effective generation of drugs is being developed that will block excess caloric absorption on the cellular level.
Let us consider, however, a more fundamental reengineering of the digestive process to disconnect the sensual aspects of eating from its original biological purpose: to provide nutrients into the bloodstream that are then delivered to each of our trillions of cells. These nutrients include caloric (energy-bearing) substances such as glucose (from carbohydrates), proteins, fats, and a myriad of trace molecules, such as vitamins, minerals, and phytochemicals, that provide building blocks and facilitating enzymes for diverse metabolic processes.
Kurzweil, as always, is a charismatic and persuasive writer, and even if you feel that his arguments are far too materialistic (as I do), they are nonetheless well worth the read..
