Different people have different opinions. Thanks to AI, Millenniumbutterfly has got his own super-smart personal assistant ①built (build) into his phone. AI always has ②an immediate answer for any question he puts to her, and even uses his answers to learn more about his ③preferences (prefer). And speaking of ④hanging (hang) out, he is hoping that self-driving cars are available soon. Self-driving cars can learn to drive in the same way that we do, and can make judgements based ⑤on information. And as they won't be susceptible to human error, they'll certainly be a lot safer. Popkid thinks it could be very ⑥useful (use) to have a more advanced form of AI, but there are other risks. Nearly every job is ⑦potentially (potential) at risk in the long run. As it is, almost 50 per cent of US jobs ⑧are (be) at risk from automation in the next 20 years. Pink_haze argues while super-intelligent AI could be the biggest leap forward in human history, if it goes wrong ⑨or falls into the wrong hands, it could also be the most dangerous. However, we have no choice but ⑩to_embrace (embrace) it and regulate it. 学科网（北京）股份有限公司 $
