人工智能会抢走所有工作吗
Emily Hanley rubs her face, then takes a breath. “I recently lost my job to AI,” she says, in a video she shared on TikTok. She was a copywriter, or someone who writes the text for brands’ webpages, online articles, email campaigns, and other marketing materials. New generative AI tools such as OpenAI’s ChatGPT, Google’s Bard, or Baidu’s Ernie excel at generating text for all sorts of purposes, including this one. Generative AI can also write code. And it’s far cheaper than hiring a person to do the same thing. In an article for Business Insider about the ordeal, Hanley wrote, “While I and countless other out-of-work copywriters are the first wave of AI collateral, the collapse of my profession is probably just the tip of the AI iceberg. ”

我们身边的机器人
In the Star Wars movies, the droid R2-D2 carries messages, puts out fires, and while trapped on Jabba the Hutt’s sail barge, even carries a tray of drinks. R2-D2 also saves the heroes’ lives on several occasions . C-3PO and R2-D2 are both servants and friends. The idea that people might create machines to do tasks for them has been around for centuries— but only in myths and science fictions. Golems, animated clay statues, march through Jewish folklore. And Greek myths describe living metal statues called Automata.
3D 打印将如何改变制造业
In fairy tales, a wizard waves a magic wand and poof! There’s a carriage or a cake or a pair of shoes. We don’t have magic wands, and probably never will. But we do have 3D printers. A 3D printer can’t make something out of nothing. But it can create just about anything you can imagine. Feed one a design for an object, and it will print that object. You just have to give it a raw material to print with. Many 3D printers are small machines—around the size of a microwave oven—so they can be carried anywhere.

大楼内的新型运载工具
At the end of the story Charlie and the Chocolate Factory by Roald Dahl, the eccentric inventor and candy – maker Willy Wonka takes young Charlie Bucket into a glass contraption that he calls a Wonkavator. It bursts through the roof of the factory and flies them out over the city. Willy Wonka says, An elevator can only go up and down, but the Wonkavator can go sideways, and slantways, and longways, and backways, and squareways, and frontways, and any other ways that you can think of.
虚拟的攻击，真实的威胁
Airplanes couldn’t take off. Ships and trucks couldn’t deliver products. Factories stopped running. Hospitals had to turn away patients. It was June 27, 2017, and an invisible enemy was attacking businesses around the world. That enemy was a computer virus. Security experts named it NotPetya because at first it seemed similar to a 2016 virus named Petya. But it was much worse than Petya. “It was the worst cyberattack ever,” says Craig Williams, a cybersecurity expert at Cisco in Austin, Texas.

互联网进入Web 3.0时代
A teenage girl wanders into her kitchen one morning. The lights come on automatically as she enters the room and her favorite music begins to play, thanks to the Internet of the future. Invisibly, it follows her every move, anticipating what she will want and need. It accesses the smart watch the girl is wearing, gathering data about her current health including body weight, heart rate, bowel movements, and how much she has exercised and slept lately. It combines this data with knowledge about how various foods have affected the health of everyone else using the Internet and smart watches. Then it speaks through the watch with the voice of a friendly virtual assistant, suggesting yogurt with granola, a healthy and enjoyable breakfast.

制造新型人体器官
The human body works like a machine. Over time, its parts wear out or get damaged. For example, disease may weaken the heart or a bone may break. When the body cannot heal itself, a doctor may repair or replace diseased or broken parts to keep the body running smoothly. Sometimes, a living or dead human donor provides a part. Donations of hearts, lungs, kidneys, bone marrow, blood, and other tissues regularly save lives. But getting new parts from other human beings isn’t the only way to accomplish this.
