(Find out some time how many people die outright in coal mining and how much radiation burning coal puts out, not to mention the mercury contamination.) While I realize you can also build nuclear reactors fueled by thorium, the real-world uranium supply has hit a bottleneck, with even talk of "peak uranium" in some quarters: Analysis: Demand to Stress Uranium Supply http://www.upi.com/Energy/analysis_demand_to_stress_uranium_supply/20070302-045726-5588r/ It also deserves mentioning that nuclear power requires a substantial fossil fuels subsidy to work. Our civilization uses energy from fossil fuels to find, mine, transport, process and assemble fissionable materials into nuclear reactors. Not to mention that the Homer Simpsons who work at nuclear power plants need gasoline to get to their jobs. How would uranium get from a mine in Australia to the U.S. without bunker fuel for the freighter, for example? On a sailing ship? I also wonder why libertarians defend nuclear power, given how deeply the state has guided its development. Without the state to absorb many of the costs and risks of nuclear energy throughout its history, would this technology have ever even arisen through spontaneous market processes? >Photovoltaics are also clearly about to be quite practical. 30 years ago >cells cost something like $600 per watt in *non*-inflation adjusted >dollars. The factories which manufacture photovoltaic devices don't run off of solar or wind power. Instead they have to use the regular power grid running off of fossil fuels, hydroelectric power or nuclear power. A real alterative to fossil fuels wouid have to cut them out of the loop altogether. >There are teenagers getting in trouble these days for sending digital >photographs of themselves giving blow jobs to each other from their camera >equipped cellphones to their friends' internet connected personal >computers.

Many morally conservative parents wouldn't consider this as evidence of "progress," and I feel sympathetic to their viewpoint even though I don't have children. (Not having children never stopped Robert Heinlein from pontificating about parenthood and childrearing. either.) >We've sequenced the human genome -- repeatedly if you count all the SNP and >other work -- and we're in striking distance of equipment that will >sequence any genome for peanuts in a few days.

As Brian Wowk and others have pointed out, none of these developments necessarily have to get translated into medical practice, especially given the current cultural and political climate; nor does it follow that these techniques will necessarily create any substantial longevity breakthrough in humans. Robin Hanson argues that most of the healthcare we consume doesn't do us any good, and we don't really know why people live as long as they do, nor why longevity in certain groups has increased lately. The supercentenarian freaks, many of whom lived in poverty much of their lives, certainly didn't ingest something like Life Extension Mix in the early and mid 20th Century to make it to at least 110 years of age. >You're totally out of touch if you think the future isn't here just because >your flying car hasn't arrived. Straw man. Edgar Swank wants a flying car. Where did I say I wanted one? >Clearly you're surrounded by more change than people can cope with, and it >is only accelerating, and you're asking "where is the future". Well open >your eyes already. Do I see "the future" in the tooth-optional Arizonans I encounter every day? (I also met a great many people like that in California.) Maybe you live in an affluent bubble somewhere, and don't have a good understanding of how many ordinary Americans live. >Mirrored single piece overalls from Hugo Gernsback magazine covers are not >the way to tell you are "in the future". People carrying their laptop >computers into coffee shops and pirating full length movies over wireless broadband via peer-to-peer networks while sipping their tea is more relevant. It doesn't matter how gadgety our lives become, if we still have to age and die. I just view a lot of this stuff as the high-tech equivalent of grave goods.
