It seems like alot is being said at this year's TransVision 2007 conference - the leading annual get-together for posthumanist thinkers. For example:
Marvin Minsky suggested that 'we' could solve any population problem by uploading the minds of 10 billion people and running them on a computer that occupies a few cubic meters and costs only a few hundred dollars to run. Sounds like a familiar, ongoing argument.
Then there is the avatar and transhumanist guru Ray Kurzweil who again claimed that longevity trends are accelerating so fast that the life expectancy will increase more than one year for each year that passes in about 15 years. In other words, if you can hang on another 15 years, your life expectancy could be indefinitely long. He projects that by 2030, AI will be ubiquitous, and most humans will be physically melded to information and other technologies.
This online article is a good brief overview of some speakers - 'Would you give up your immortality to ensure the success of a posthuman world?'
Again, so much emphasis upon re-designing the body of the human, and virtually little or no conception of the evolutionary growth of Spirit and the nervous system... typical of the scientific materialistic, atomistic mindset...
