The human brain contains 10 thousand million cells and each of these mayhave a thousand connections. Such enormous numbers used to discourage us andcause us to dismiss the possibility of making a machine with human-likeability,but now that we have grown used to moving forward at such a pace we canbe less sure. Quite soon，in only 10 or 20 years perhaps，we will be able toassemble a machine as complex as the human brain,and if we can we will. It maythen take us a long time to render it intelligent by loading in the rightsoftware (软件)or by altering the architecture but that too will happen.
I think- it certain that in decades not centuries*machines of silicon(桂)will arise first to rival and then exceed their human ancestors. Once theyexceed us they will be capable of their own design. In a real sense they will beable to reproduce themselves. Silicon will have ended carbon‘s long control. Andwe will no longer be able to claim ourselves to be the finest intelligence inthe knowledge.
As the intelligence of robots increases to match that of humans and astheir cost dec ines through economies of scale we may use them to expand ourfrontiers first on earth through their alnlity to withstand environments,harmful to ourselves. Thus deserts may bloom and the ocean beds be mined.Further ahead, by a combination of the great wealth this new age will bring andthe technology it will provide, the construction of a vast,man-created world inspace，home to thousands or millions of people， will be within our power.
It can be inferred from the passage that_.
A. after the installation of a great number of cells and connections robotswill be capable of reproduction
B. with the rapid development of technology people have come to realize thepossibility of making a machine with human-like ability
C. once we make a machine as complex as the human brain»it will possessintelligence
