[audio]http://sound.yywz123.com/tingbbs/cet4/cet420110923.mp3[/audio]The human brain contains 10 billion cells and each of these may have a thousand connections.Such enormous numbers used to discourage us and
cause us to dismiss the possibility of making a machine with human-like ability,but now that we have grown used to moving forward at such a pace we can be less sure.(1)_________________________.It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture but that too will happen.I think it certain that in decades,not centuries, machines of silicon will arise first to rival and then exceed their human ancestors.Once they exceed us they will be capable of their own design.In a real sense they will be able to reproduce themselves.Silicon will have ended carbon's long control.(2)_________________________.As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale.we may use them to expand our frontiers,first on earth through their ability to withstand environment,harmful to ourselves.(3)_________________________.Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide the construction of a vast,man-created world in space will be within our power.
**** Hidden Message ***** 1)Quite soon,in lowly ten to twenty years perhaps,we would be able to simply machine as compress as human brain,and if we can ,we will
2)And we will no longer be able to claim of south to be the finance intelligence in the low universe
3)Thus,that may bloom and the ocean that be mined [p=30, 2, left][font=Times New Roman][color=#000000][size=14pt]1
