问题     Very soon, unimaginably powerful technologies will remake our lives.This could have dangerous consequences, especially because we may not even understand the basic science underlying them.There’s a growing gap between our technological capability and our underlying 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, artificial intelligence and biotechnology.The benefits they will bring are beyond doubt but they are potentially very dangerous.In the field of artificial intelligence there are prototype designs for something that might be 50,000 million times smarter than the human brain by the year 2010.The only thing not feasible in the film Terminator is that the people win.If you’re fighting against technology that is that much smarter than you, you probably will not win.We’ve all heard of the grey goo problem that self-replicating nanotech devices might keep on replicating until the world has been reduced to sticky goo, and certainly in biotechnology, we’ve really got a big problem because it’s converging with nanotechnology.Once you start mixing nanotech with organisms and you start feeding nanotech-enabled bacteria,    we can go much further than the Borg in Star Trek, and those superhuman organisms might not like us very much.
    We are in a world now where science and commerce are increasingly bedfellows.The development of technology is happening in the context of global free trade regimes which see technological diffusion embedded with commerce as intrinsically a good.We should prepare for new and unfamiliar forms of argument around emerging technologies.
It can be inferred from the text that the author______.
选项 A、thinks people overestimate the capabilities of technology
B、is not optimistic that artificial intelligence will always be used positively
C、thinks that we should take science fiction movies more seriously
D、believes artificial intelligence is the greatest threat we face technologically
答案B
解析 文中第2段具体分析探讨了人工智能、纳米技术和生物技术的潜在危险。从中可知，作者对人工智能的积极应用并不乐观。因此B项为正确答案。
