Then we can get ready for the breakthroughs that could come at the end of the next century and the technology is comparable to mapping our genes: plotting the 10 billion or more neurons of our brain. With that information we might someday be able to create artificial intelligences that think and experience consciousness in ways that are indistinguishable from a human brain. Eventually we might be able to replicate our own minds in a dry-ware machine, so that we could live on without the wetware of a biological brain and body. The 20th centurys revolution in infotechnology will thereby merge with the 21st centurys revolution in biotechnology. But this is science fiction. Lets turn the page now and get back to real science.
