X-Message-Number: 32356 From: "John de Rivaz" <> References: <> Subject: Re: Organic progress model versus the Drunkard's Walk Date: Wed, 3 Feb 2010 17:45:42 -0000 As far as rockets are concerned, I am wondering whether the lack of enthusiasm is because that although they do the job, they are really quite impractical on an econmic basis for getting out of gravity wells. Clarke's idea of the space elevator seemed like a wild fantasy at the time of inception, but nanotechnology has made it look more of a possibility. The trouble is, that it could still be too long for most aspiring astronauts alive today before the materials are found to implement it. There is a similar parallel with cures for aging. Heroic surgery is a bit like rockets - expensive and capable for helping only a few people, and not achieving much in terms of maximum lifespan. With the passing years, nanotechnological methods are looking more feasible. But they are too late for those alive today. Consider the history of the automobile. The first internal combusion engine driven vehicle appeared in 1807 http://www.cybersteering.com/trimain/history/ecars.html#3 A modern reconstruction of the vehicle was said to be almost impossible to drive. The idea was probably considered totally impractical by those living in the early 19th century. Horses eat grass rather than need fuel, can look where they are going, and go faster than that car. It was over a hundred years before it developed into a popular product. Even then Dr Benz felt that only 2000 or so people in the entire world would be capable of driving one of his. Humans may well venture into space and live indefinitely - but not current generations, unless cryonics works, both legally and scientifically. -- Sincerely, John de Rivaz: http://John.deRivaz.com for websites including Cryonics Europe, Longevity Report, The Venturists, Porthtowan, Alec Harley Reeves - inventor, Arthur Bowker - potter, de Rivaz genealogy, Nomad .. and more ----- Original Message ----- <del>The Obama Administration's relinquishment of manned space travel, a key component in the progress mythology from way back, suggests that the drunkard's walk better fits the data than the organic model. Human civilization has no more inherent reason to keep building rockets and sending men into orbit than it had to keep building pyramids. <del> Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=32356
