阅读理解 On August 29th ， Elon Musk, the boss of Tesla, an electric-car maker, announced that some of his customers would find that their cars had suddenly developed the ability to drive farther on a single battery charge. Like many modern vehicles, Mr. Musk's products are best thought of as Internet-connected computers on wheels. The cheaper models in Tesla' line-up have parts of their batteries disabled by the car's software in order to limit their range. At the tap of a keyboard in Palo Alto, the firm was able to remove those restrictions and give drivers temporary access to the full power of their batteries. Mr. Musk's computerized cars are just one example of a much broader trend. As computers and connectivity become cheaper, it makes sense to bake them into more and more things that are not, in themselves, computers creating an "Internet of things", or IoT. It is a slow revolution that has been gathering pace for years, as computers have found their way into cars, telephones and televisions. But the transformation is about to speed up. One forecast is that by 2035 the world will have a trillion connected computers, built into everything from food packaging to bridges and clothes. Such a world will bring many benefits. Consumers will get convenience. Amazon's Ring smart doorbells, for instance, come equipped with motion sensors(运动传感器) and video cameras. Working together, they can also form what is, in effect, a private CCTV(closed circuit television) network, allowing the firm to offer its customers a "digital neighborhood-watch" scheme and pass any interesting video along to the police. Business will get efficiency, as information about the physical world that used to be temporary and uncertain becomes concrete and analyzable. Connected cows can have their eating habits and vital signs tracked in real time, which means they produce more milk and require less medicine when they fall ill. Such gains are individually small but, mixed again and again across an economy, they are the raw material of growth potentially a great deal of it. In the long term, though, the most noticeable effects of the IoT will be on how the world works. One way to think of it is to regard it as the second phase of the Internet. Ever, more companies will become tech companies; the Internet will become widespread. As a result, a series of unsolved arguments about ownership, data, competition and security will spill over from the virtual world into the real one. （1） Why does the author mention Elon Musk? A .
