阅读理解 Changing technology stimulates (刺激) the brain and increases intelligence. But that may only be true if the technology challenges us. In a world run by intelligent machines, our lives could get a lot simpler. Would that make us less intelligent?
After the Industrial Revolution, machines began to replace manual workers. The process played out in agriculture as well as manufacturing so that groups of agricultural workers were replaced and forced to move to cities to make a living.
When machines took away much of the manual work, people became less physically active and gained weight. The sedentary (久坐的) lifestyle contributed to a worldwide spreading of overweight and related metabolic disorders such as heart disease, secondary diabetes and kidney disease .
As our bodies rested, our brains were forced to work harder, however. It is much more difficult to drive through an overcrowded modern city than it is to move around in a small rural village, for instance. Modern jobs are also more complex and urgent and they require more education because employees need to process new information quickly. Even during our leisure time, our brains work harder due to greater availability of books and explosion of audiovisual media, for entertainment, study, music, news, and so forth.
Now in the Internet age, the amount of information grows fast along with the advance of electronic technologies. The number of people with whom we interact electronically grows by leaps and bounds thanks to the ease of use of social media like Facebook and Twitter.
All of this extra work for our brains makes us more intelligent. That helps explain why human intelligence increases steadily from generation to generation in all developed countries, a phenomenon named the Flynn Effect. Of course, there are other reasons, including improved nutrition, better medical practices that reduce brain damage, and improved sanitation and public health that reduce diseases of childhood.
In the P.G Wodehouse novels, Bertie Wooster got away with being a fool because Jeeves was there to back him up with superior brain power. Similarly, people of the future are at risk of being less intelligent because machines will do their thinking for them.
Artificial intelligence is taking over many human jobs. For instance, planes are being flown much of the time by automatic pilots. Moreover, the complex problem of controlling air traffic around large modern airports is also achieved by artificial intelligence that operates well beyond the capability of mere human air traffic controllers.
Artificial intelligence exists in many fields of modern life for the simple reason that intelligent machines can already outperform humans, including some aptitudes (天资) which were once thought to be a human advantage, such as playing chess or recalling details in a game of Jeopardy.
Machine intelligence is increasing much faster than human intelligence. As machines get smarter, they will do more of our thinking for us and make life easier.
Instead of struggling to identify ourselves to some electronic system via passwords that are secure only if they are hard to remember, the system will work harder to identify us using biometrics (生物测定学) such as fingerprints or even the individual sound of our hearts. More technologies of the future may also be voice-activated so that we will talk with machines much as we would talk to a friend.
In the future, the electronic assistant will develop to the point where it serves similar functions as a real living chief male servant of a house, fulfilling requests such as: “Organize a dinner party for six on Thursday, Jeeves, and invite the usual guests .”
At that point, our long struggle with challenging technologies is at an end. Like Bertie Wooster, we can take it easy knowing that the hard work of planning and organizing is being done by a better brain—the electronic assistant. Starved of mental effort, our brains will return to an earlier or less advanced form.
The future is still in the fog.
