Successful businesses tend to continue implementing the ideas that made them successful. But in a rapidly changing world, ideas often become obsolete overnight. What worked in the past won’t necessarily work in the future. In order to thrive in the future, you must constantly create new ideas for every aspect of your business. In fact, you must continually generate new ideas just to keep your head above water. Businesses that aren’t creative about their future may not survive.
Although Bill Gates is the richest, most successful man on the planet, he did not anticipate the Internet. Now he’s scrambling to catch up. If Bill Gates can miss a major aspect of his industry, it can happen to you in your industry. Your business needs to continually innovate and create its future.
Gates is now constantly worried about the future of Microsoft. Here’s what he said in a recent interview in U. S. News World Report: "Will we be replaced tomorrow No. In a very short time frame, Microsoft is an incredibly strong company. But when you look to the two-to three-year time frame, I don’t think anyone can say with a straight face that any technology company has a guaranteed position. Not Intel, not Microsoft, not Compaq, not Dell, take any of your favorites. And that’s totally honest."
You may remember that in 1985 the Cabbage Patch Kids dolls were the beat-selling toy on the market But after Coleco Industries introduced their sensational line of dolls they became complacent and didn’t create any new toys worth mentioning. As a result, Coleco went bankrupt in 1988.
The most successful businesses survive in the long term because they constantly reassess their situations and reinvent themselves accordingly. The 3M Company has a 15% rule: Employees are encouraged to spend 15% of their time developing new ideas on any project they desire. It’s no surprise, then, that 3M has been around since 1902.
Most businesses are not willing to tear apart last year’s model of success and build a new one. Here’s a familiar analogy to explain why they are lulled into complacency. Imagine that your business is like a pet of lobsters. To cook lobsters, you put them into a pot of warm water and gradually turn up the heat. The lobsters don’t realize they’re being cooked because the process is se gradual. As a result, they become complacent and die without a struggle. However, if you throw a lobster into the pot when the water is boiling, it will desperately try to escape. This lobster is not lulled by a slowly changing environment. It realizes instantly that it’s in a bad environment and takes immediate action to change its status.
A:constant reassessment of their situations B:15% rule C:reinvention D:being around since 1902

| {{B}}The Robot
Man{{/B}} ? ?According to Hans Moravec,universal robots will take over all the physical activities that we engage in,leaving us with little to do. Moravec sees four generations on the road to true universal robots. The first generation will be here by 2010 and will consist of free-ranging robots that can navigate by building an internal mental map of their surroundings. In new situations they’ll be able to adapt, unlike today’s mobile ?industrial robots. These robots will have the computing power to cope with simple speech and text recognition,and will be used for tasks such as domestic cleaning. ? ?The second generation will arrive around 2020 and will be distinguished by the ability to learn. Second ?generation robots are programmed with sets of primitive tasks and with feedback that provide"pleasure" and "pain"stimuli. For example,a collision provokes a negative response,a completed task would be positive. ? ?ove forward another ten years to 2030 and you get to generation three. This robot can build internal simulations of the world around it. Before beginning a task, it can imagine what will happen in order to predict problems. If it has a free moment,it can replay past experiences and try variations in order to find a better way of doing things next time. It could even observe a person or another robot performing a task and learn by imitation. For the first time,we have here a robot that can think. ? ?By the time we get to generation four in 2040, Moravec predicts that robots will be able to match hu- man reasoning and behaviour; generalise abstract ideas from specific experience; and, conversely, compile detailed plans of action from general commands such as’earn a living’ or ’make more robots’ ? ?The Moravec manifesto(宣告)runs something like this. As robots start to become useful in generation ?one,they’ll begin to take on many tasks in industry. Driven by the availability of this cheap and tireless ?labour force,the economy will boom and the demand for robots will grow so rapidly that they will soon become low-cost commodity items. So much so that they’ll move into the home,where the domestic robot will relieve us of many chores. ? ?With increasing automation in generations two and three, the length of the average working day will plummet,eventually to near zero. Most people will be unemployed as robots take over not just primary industry, but the service economy too. Moravec sees the fourth generation as an opportunity to surpass our human limitations. ? ?These future machines will be our "mind children". Like biological children of previous generations, they will embody humanity’s best hope for a long-term future. |
