What might be good for you is probably bad for someone or something else. What we usually consider to be good is rarely beneficial to everyone: it depends on who you are and where you stand. As Shakespeare said in Hamlet, there is nothing either good or bad, but thinking makes it so. And our diverse thinking on good is reflected by the 50 or more definitions for the word "good" offered by most dictionaries.

　　The same goes for innovation. Is an innovation good if it solves your problems or lets you make money? Definitely. But what if it also causes people to lose their jobs? Or, as is more often the case, what if after people spend days learning to use the innovation, there is little benefit, or their lives become more complicated? And then consider plastics, typewriters and televisions, innovations that have brought many good things to the world. But what if the 2－litre soda bottles rested forever in landfills, the typewriters were used to schedule trains to Auschwitz, or millions of children watched hours of televisions in lieu of reading or doing sports? Can we call these, and others like them, innovations because they're good in the largest sense? And, despite all the positive revolutions they've brought to the world, personal computers leave tons of toxins and chemicals every time they're replaced by newer machines.

　　There's no easy answer to the question whether innovation is good, leaving plenty of room for the belief of "all innovations are good" to survive. We have so much history with innovation as the driving force for our culture, economy and psychology that our confidence in innovation approximates(接近) faith. But there is at least one truth: all innovations have good and bad effects regardless of the intention of the innovators. If we accept this, we can reevaluate our judgment on innovations.

　　4．What's the main idea of the first paragraph?
