自动驾驶时代真的来了吗
人工智能时代来临后，自动驾驶开始成为各界共同看好的“AI技术突破口”，而乘用车行业作为整个汽车产业最大的市场，也承载着自动驾驶从业者们的梦想。
什么是无人驾驶？目前，行业以自动/无人驾驶的自动化程度，将这项技术技术分为了五个等级：
L1级——以人工驾控为主，加入ABS防锁死刹车、TRC系统等提供安全性的技术。
L2级——部分自动化驾驶，如特斯拉AutoPilot，系统可自动控制油门、刹车和跟车行驶。
L3级——有条件的自动化驾驶，如奥迪新款A8搭载的自动驾驶系统，驾驶员可在一定条件下“解放双手”，车辆完全由计算机控制。
L4：高度自动化的自动驾驶，车辆将在目的地设置后自主行驶，驾驶员只需在特定区域进行人工干预。
L5：完全自动驾驶，即无人驾驶，车内可不配备驾驶座及驾驶机构，任何环境下都无需人工介入操控。
事实上，从2016年起，自动/无人驾驶开始成为资本和科技界追逐的风口，而随着越来越多智能汽车产品的落地，以及自动驾驶公司开始出现各种各样的落地难题，使消费者对无人驾驶的终极幻想逐渐破灭。
当然，技术还是要发展的，基础科学的进步和交通基建的改造都需要时间，而无人驾驶也终有一天能够实现——而在此之前，整个行业首先要攻克的是中低级自动驾驶技术，以及相关基建的发展。
就自动驾驶本身来看，包含着车辆控制、车辆工程、传感器、人工智能算法、大数据、云计算等多个领域的技术，同时还需生产方在安全方面有足够的认知，仅靠其中一部分都是无法实现自动驾驶的。
现阶段，能够将这些技术整合并快速落地的企业，则是以整车厂为主。例如前文我们提到的特斯拉、奥迪等国际大厂，都开始逐步推出前装了不同级别自动驾驶系统的车型。
另一方面，国内各大整车厂也纷纷开始布局智能驾驶或自动驾驶技术。政策方面，根据罗兰贝格对自动驾驶发展的研报，到2020年，有望在城市特定区域开放道路进行自动驾驶车辆测试，并在部分高速公路允许L3自动驾驶，这对于整车厂来讲绝对是好消息。
目前，各大厂商都在以自己的快速前行，且聚焦点则不尽相同，但自动驾驶作为“取代人操控车”的技术，消费者最关注的还是安全问题。而关于汽车安全与智能驾驶、自动驾驶的结合，国内车企吉利则已进行多项布局。
从收购主打安全的国际汽车品牌沃尔沃，到在量产车辆上加入多项辅助安全的智能驾驶技术，吉利早已“悄悄”在为自动驾驶技术的落地进行先期布局。
吉利在自动驾驶方面的布局并非“拍脑袋”的决定，这与其品牌目标和近年来的快速发展不无关联。继在成为杭州亚运会官方汽车服务合作伙伴之后，吉利宣布将于2022年实现区域范围内完全自动驾驶等智慧出行体验，为杭州亚运会提供全方位服务。
与杭州亚运会的合作，能够看出吉利对自动驾驶技术创新的决心以及相关部门对企业的认可，期待吉利能够安全和稳定作为自动驾驶发展的基础，为消费者带来技术过关、安全性能过硬的产品。

A Night the Earth didn’t Sleep Strange things were happening in the countryside of northeast Hebei. For three days the water in the village wells rose and fell, rose and fell. Farmers noticed that the well walls had deep cracks in them. A smelly gas came out of the cracks. In the farmyards, the chickens and even the pigs were too nervous to eat. Mice ran out of the fields looking for places to hide. Fish jumped out of their bowls and ponds. At about 3:00 am on July 28, 1976, some people saw bright lights in the sky. The sound of planes could be heard outside the city of Tangshan even when no planes were in the sky. In the city, the water pipes in some buildings cracked and burst. But the one million people of the city, who thought little of these events, were asleep as usual the night.
At 3:42 am everything began to shake. It seemed as if the world was at an end! Eleven kilometers directly below the city the greatest earthquake of the 20th century had begun. It was felt in Beijing, which is more than two hundred kilometers away. One-third of the nation felt it. A huge crack that was eight kilometers long and thirty meters wide cut across houses, roads and canals. Steam burst from holes in the ground. Hard hills of rock became rivers of dirt. In fifteen terrible seconds a large city lay in ruins. The suffering of the people was extreme. Two-thirds of them died or were injured during the earthquake. Thousands of families were killed of injured reached more than 400,000.
But how could the survivors believe it was natural? Everywhere they looked nearly every thing was destroyed. All of the city’s hospitals, 75% of its factories and buildings and 90% of its homes were gone. Bricks covered the ground like red autumn leaves. No wind, however, could blow them away. Two dams fell and most of the bridges also fell or were not safe for traveling. The railway tracks were now useless pieces of steel. Tens of thousands of cows would never give milk again. Half a million pigs and millions of chickens were dead. Sand now filled the wells instead of water. People were shocked. Then, later that afternoon, another big quake which was almost as strong as the first one shook Tangshan. Some of the rescue workers and doctors were trapped under the ruins. More buildings fell down. Water, food, and electricity were hard to get. People began to wonder how long the disaster would last.
All hope was not lost. Soon after the quakes, the army sent 150,000 soldiers of thousands of people were helped. The army organized teams to dig out those who were trapped and to bury the dead. To the north of the city, most of the 10,000 miners were rescued from the coal mines there. Workers built shelters for survivors whose homes had been destroyed. Fresh water was taken to the city by train, truck and plane. Slowly, the city began to breathe again.

地球的一个不眠之夜
河北省东北部的农村不断有些怪事发生：三天来,村子里的井水升升降降,起起伏伏.农夫注意到,水井的井壁上有深深的裂缝,裂缝里冒出臭气.农家大院里的鸡,甚至猪都紧张得不想吃食.老鼠从田地里跑出来找地方藏身.鱼缸和池塘里的鱼会往外跳.在1976年7月28日凌晨3点左右,有些人看到天上一道道明亮的光.即使天空没有飞机,在唐山城外也可以听到飞机声.在市内,有些建筑物里的水管爆裂开来.但是,唐山市的一百万居民几乎都没有把这些情况当一回事,当天晚上照常睡着了.
在凌晨3点42分,一切都开始摇晃起来.世界似乎到了!二十世纪最大的一次地震就在唐山市正下方11公里处发生了.100公里以外的北京市都感到了地震,全国1 / 3的地方都有震感.一条8公里长30米宽的巨大裂缝横穿房舍、马路和渠道.地上一些洞穴冒出了蒸气.石头山变成了泥沙河,在可怕的15秒钟内,一座大城市就沉沦在一片废墟之中.人们遭受的灾难极为深重.2/3的人在地震中死去或受伤.成千上万个家庭遇难,许多孩子变成了孤儿.死伤的人数达到40多万.
幸存的人们又怎么能相信这是自然现象呢?人们无论朝哪里看,哪里的一切都几乎被毁了.所有的市内医院、75%的工厂和建筑物、90%的家园都消失了.残砖就像秋天的红叶覆盖着大地,然而它们是不可能被风刮走的.两座大坝垮了,多数桥梁不是塌了就是无法安全通行了.铁轨如今成了一条条废钢.好几万头牛再也挤不出奶来.50万头猪和几百万只鸡全都死了.井里满是沙子,而不是水.人们惊呆了.接着,在下午晚些时候,又一次和第一次一样的强烈的地震震撼着唐山.有些医生和救援人员被困在废墟下面.更多的房屋倒塌了.水、电和食物都很难弄到.人们开始纳闷,这场灾难还会持续多久.
不是所有的希望都破灭了.地震后不久,部队派了15万名战士到唐山来协助救援人员,数十万的人得到了救助.部队人员组成小分队,将受困的人们挖出来,将死者掩埋.在唐山市的北边,有一个万名矿工的煤矿,其中多数人得救了.援救人员为那些家园被毁的幸存者盖起了避难所,用火车、卡车和飞机向市内运来了水.慢慢地、慢慢地,这座城市又开始出现了生机.
Elias’ Story My name is Elias. I am a poor black worker in South Africa. The time when I first met Nelson Mandela was a very difficult period of my life. I was twelve years old. It was in 1952 and Mandela was the black lawyer to whom I went for advice. He offered guidance to poor black people on their legal problems. He was generous with his time, for which I was grateful.
I needed his help because I had very little education. I began school at six. The school where I studied for only two years was three kilometers away. I had to leave because my family could not continue to pay the school fees and the bus fare. I could not read or write well. After trying hard, I got a job in a gold mine. However, this was a time when one had got to have a passbook to live in Johannesburg. Sadly I did not have it because I was not born there, and I worried about whether I would become out of work.
The day when Nelson Mandela helped me was one of my happiest. He told me how to get the correct papers so I could stay in Johannesburg. I became more hopeful about my future. I never forgot how kind Mandela was. When he organized the ANC Youth League, I joined it as soon as I could. He said:
“The last thirty years have seen the greatest number of laws stopping out rights and progress, until today we have reached a stage where we have almost no rights at all.”
It was the truth. Black people could not vote or choose their leaders. They could not get the jobs they wanted. The parts of town in which they had to live were decided by white people. The places outside the towns where they were sent to live were the poorest parts of South Africa. No one could grow food there. In fact as Nelson Mandela said:
“…we were put into a position in which we had either to accept we were less important or fight the government. We chose to attack the laws. We first broke the law in a way which was peaceful; when this was not allowed…only then did we decide to answer violence with violence.”
As a matter of fact, I do not like violence… but in 1963 I helped him blow up some government buildings. It was very dangerous because if I was caught I could be put in prison. But I was happy to help because I knew it would help us achieve our dream of making black and white people equal.伊莱亚斯的故事
我的名字叫伊莱亚斯.我是南非的一个穷苦的黑人工人.第一次见到纳尔逊·曼德拉的时候,是我一生中非常艰难的时期.（当时）我才12岁,那是在1952年,曼德拉是我寻求帮助的一位黑人律师.他为那些穷苦黑人提供法律指导.他十分慷慨地给予我时间,我为此非常感激.
由于我所受的教育很少,所以我需要他的帮助.我六岁开始上学,我仅仅在那里读了两年的学校有里远.我不得不辍学,因为我的家庭无法继续支付学费和交通费.我既不太会读,也不怎么会写.几经周折,我才在一家金矿找到一份工作.然而在那个时候,你要想住在约翰内斯堡就非得要有身份证不可.糟糕的是我没有这个证件,因为我不是在那里出生的,我很担心我是不是会失业.
纳尔逊·曼德拉给予我帮助的那一天是我一生中最高兴的日子.他告诉我要想在约翰内斯堡立住脚,应当如何获取所需证件.我对自己的未来又充满了希望.我永远也忘记不了他对我的恩情,当他组织了非国大青年联盟时,我马上就参加了这个组织.他说：“过去30年来所出现的大量法律剥夺我们的权利,阻挡我们的进步,一直到今天,我们还处在几乎什么权利都没有的阶段.”
他说的是真话.当时黑人没有选举权,他们无权选择他们的领导人.他们不能做自己想要做的工作.他们所能住的城区都是由白人决定的.他们被打发去住的城外地区是南非最贫穷的地区.在那儿,没有人能够种庄稼.事实上,就像拉尔逊·曼德拉所说的：
“……我们被置于这样一个境地：要么我们接受低人一等的现实,要么跟作斗争.我们选择向法律进攻.首先我们用和平的来破坏法律,而当这种也得不到允许时,……只有到这个时候,我们才决定用暴力反抗暴力.”
事实上,我并不喜欢暴力,……但是在1963年的时候,我帮助他炸毁了一些大楼.那是很危险的事情,因为如果我被抓住了,可能就会被关进监狱.但是,我乐于帮忙,因为我知道,这是为了实现我们的黑人和白人平等的梦想.

怎么了
是大泡沫，今年就是大幅去泡沫的过程。
谁也都想象不到，最高能上涨至将近20000美元，而且涨的最快的年份是2017年，那时候年初还不到5000美元。
的疯狂上涨，让一部分投资家觉得，再往上涨，拉盘投资成本太大了，而且也纵观思考这个科技新事物，到底值这个价钱么。还有如果只有这一种币还好，关键是还各种各样的币。
OK币、等等，百多来种币都过来凑热闹，一个上科技研究都没取得成就，这么多币都过来凑热闹，这明显就是要爆炸的节奏。而且后来的这些币看起来更没有实际支撑，最起码还有技术撑腰，那些新币种就更如同空中楼阁了，所以跌幅比还要凶猛。
科技进步，将会是接下来上涨、下跌的主要动力。但可以拿与美国股票比啊，如果许多美国股票都很便宜，如苹果、脸书、微软等，那价格也就在1000美元之下。
