有人说机器人的使命，应该是帮助人类做那些人类做不了的事，而不是代替人类。技术变革会夺取一些人低端繁琐的工作岗位，最终也会创造更高端更人性化的就业机会。例如，历史上铁路的出现抢去了很多挑夫的工作，但是又增加了千百万的铁路工人。人工智能也是一种技术变革，人工智能也将促进人类社会的发展，有人则不以为然。

请帮忙给出每个问题的正确答案和分析，谢谢！

I can pick a date from the past 53 years and know instantly where I was , what happened in the news and even the day of the week. I’ve been able to do this since I was four.

I never feel overwhelmed with the amount of information my brain absorbs my mind seems to be able to cope and the information is stored away realy. When I think of a sad memory, I do what everyone does- try to put it to one side. I don’t think it’s harder for me just because my memory is clearer. Powerful memory doesn’t make my emotions any more acture or vivid. I can recall the day my grandfather died and the sadness I felt when we went to the hosptital the day before. I also remember that the musical paly Hamopened on the Broadway on the same day- they both just pop into my mind in the same way.

Most people would define optimism as endlessly happy, with a glass that’s perpetually half fall. But that’s exactly the kind of false deerfulness that positive psychologists wouldn’t recommend. “Healthy optimists means being in touch with reality.” says Tal Ben-Shahar, a Harvard professor, According to Ben- Shalar,realistic optimists are these who make the best of things that happen, but not those who believe everything happens for the best.

Ben-Shalar uses three optimistic exercisers. When he feels down-sag, after giving a bad lecture-he grants himself permission to be human. He reminds himself that mot every lecture can be a Nobel winner; some will be less effective than others. Next is reconstruction, He analyzes the weak lecture, leaning lessons, for the future about what works and what doesn’t. Finally, there is perspective, which involves acknowledging that in the ground scheme of life, one lecture really doesn’t matter.
