Technology: Taking the good without the bad?
Very soon, unimaginably powerful technologies will remake our lives．This could have dangerous consequences, especially because we may not even understand the basic science underlyi ng them．There’s a growing gap between our technological capability and our basic scientific understanding．We can do very clever things with the technology of the future without necessarily understanding some of the science underneath, and that is very dangerous．
The technologies that are particularly dangerous over the next hundred years are nanotechnology （纳米技术）, artificial intelligence and biotechnology．The benefits that they will bring are beyond doubt．But they are going to be very, very dangerous．I’m working in the field of artificial intelligence．I have a model design for something that might be 50,000 million times smarter than the human brain．Target date is 2010．The only thing that's not possible in the film Terminator（终结者） is that the people win．If you're fighting against technology w hich is 50,000 million times smarter than you, you probably will not win．
Nanotechnology．We've all heard of the grey glue problem, that self-replicating nanotech devices might keep on copying until the world has become sticky glue．And certainly in biotechnology, we've really got a big problem because it's converging with nanotechnology and IT．Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria, we can really go an awful lot further than the Borg in Star Trek（星际迷航）．And those superhuman organisms might not like us very much．
Eventually these technologies will become routine．That’s a threat to humanity．I don’t think it’s possible to slow it down．So what we need to do is accelerate the scientific research and try to get some extra tools．The problems facing us in the future are getting bigger and bigger．I think if we don’t get some proper science done, the future is hopeless indeed．
