ChatGPT is a prototype (原型) dialogue-based AI chatbot (聊天 机 器人 ) which can understand natural human language and creating impressively detailed human-like written text. The new AI was created by OpenAI, a research center founded by Elon Musk. Musk co-founded the new company with other bosses. The research centre aims to advance digital intelligence in a way that benefits humans.

ChatGPT works by being trained on a large amount of text from the Internet using AI and machine learning. The system is designed to provide information and answer questions through a traditional interface (界面) .

Early users have described the technology as a tool to replace to Google because it can provide descriptions, answers, and solutions to different kinds of questions. Real-world applications could include producing content for websites, answering customer questions, providing recommendations (推荐) , and creating automated (自动化的) chatbots. OpenAI CEO Sam Altman said the system is “an early model of what’s possible.” He hopes to produce helpful assistants that talk to users, answer questions, and give advice. In the future, these assistants could perform tasks for users and even discover new knowledge.

There has been prediction that jobs dependent on content production, such as playwrights, protessors, programmers, and journalists, could be obsolete because of ChatGPT. However, at its current stage, the chatbot lacks slight differences, critical thinking skills, and ethical (道德的) decision-making ability which are necessary for successful journalism. In addition, its knowledge base ends in 2021, which means that some questions and searches are useless now. ChatGPT can also provide incorrect or misleading answers, because it is short of a source of truth in the data used to train the model.

In short, ChatGPT is a powerful AI chatbot and it may be used in various industries, but it is still in its early stages and has limitations. As AI technology continues to evolve, we can expect more advanced chatbots like ChatGPT in the future.

How do you pay for things in a shop? Perhaps you like the touchable reliability of hard cash? Maybe the financial flexibility of a credit card suits you better? Or perhaps you prefer the simple convenience of a smartphone?

Whatever you use today, experts believe all these methods could soon become outdated. Instead, we will use our bodies: our eyes, our fingerprints, even our mere presence in the store. In fact it's happening already. Amazon are trialing stores which have no checkouts, where   technology tracks the items you've taken from the shelves and deducts（扣除） the total from your   account when you leave the shop.

French supermarket Monoprix takes a different path: you choose your groceries and leave them with a human cashier. You then leave the shop while the cashier adds up your bill,   charges your account, and organizes delivery to your home.

Amir, CEO of Barclaycard predicts that such new developments mean the end of the plastic credit card. Instead, wearable items such as rings, necklaces and key chains will carry chips（芯片） that allow shoppers to shop, going between the web, an app or in store.

And while all the above payment methods are supported by accounts held in traditional currencies, let's not forget the rise of alternatives such as Litecoin. Virtual（虚拟） currencies can rise in value very quickly. One such possibility is explored in the movie In Time. It imagines a futuristic society in which the currency is time itself, where people trade the amount of time they have left to live.

Or perhaps we'd do better to wind back the clock to the simpler financial world of the equal exchange economy. While the term recalls images of bags of grain and herds of sheep being exchanged in ancient times, there are signs that are making a comeback in today's world of modern technology. Maybe the only thing we know for certain is that money will keep updating.

The white rhinoceros (犀牛) holds near threatened state due to destructive hunting. Scientists are working hard to stop this and they’re doing it with some pretty cool drone (无人机) tech.

One of the biggest dangers to endangered animals in the modern day comes from hunting, which claims the lives of hundreds of white rhinos every year. However, while rangers (护林者) and regular guarding can help in stopping hunters from certain areas, they are often well-armed and unafraid to fire upon those hoping to protect the rhinos. This is where drones come in—if preservation researchers work in these areas there would be a real danger of coming into contact with the hunters, and their lives might well be at risk. By having drones collect data, movement patterns and numbers of animals, biologists are able to avoid many of these risks.

But drones aren’t only used to collect information in dangerous areas—they can also be sent into the skies above difficult-to-reach areas to get data that would otherwise be tough to collect. The endangered animals are usually found in thick jungle, and organizing a team for exploration can be expensive, time-taking, and require a great deal of bodies and planning. Instead, researches can send drones over the forest to get data about the habitat of the animals, and perhaps even get high quality images of them. This information can be extremely valuable when it comes to an on-foot exploring, as researchers can get up-to-date information on the whereabouts of the animals as they move. In this situation, human-led surveys will still offer better results, but drones can play a huge part in the preservation process.

The downside currently is the cost, which can run into tens, if not thousands, of dollars. However, drone tech is still becoming a more achievable option in the fight against extinction.
