4 . Given the buzz it’s created, there’s a good chance you’ve heard about ChatGPT. It’s an interactive chatbot powered by machine learning. The technology has basically devoured the entire Internet, reading the collective works of humanity and learning patterns in language that it can recreate. All you have to do is give it a prompt (提示), and ChatGPT can do an endless array of things: write a story in a particular style, answer a question, explain a concept, compose an email, write a college essay and it will spit out coherent, seemingly human-written text in seconds. The technology is both awesome and terrifying.

22-year-old Edward Tian is working feverishly on a new app to combat misuse of ChatGPT.

Over the last couple years, Tian has been studying an AI system called GPT-3, a predecessor to ChatGPT that was less user-friendly and largely inaccessible to the general public because it was behind a paywall. As part of his studies this fall semester, Tian researched how to detect text written by the AI system while working at Princeton’s Natural Language Processing Lab.

Then, as the semester was coming to a close, OpenAI, the company behind GPT-3 and other AI tools, released ChatGPT to the public for free. For the millions of people around the world who have used it since, interacting with the technology has been like getting a peek into the future; a future that not too long ago would have seemed like science fiction.

For many users of the new technology, wonderment quickly turned to alarm. How many jobs will this kill? Will this empower nefarious (恶意的) actors and further corrupt our public discourse? How will this disrupt our education system? What is the point of learning to write essays at school when AI which is expected to get exponentially better in the near future can do that for us?

Tian had an idea. What if he applied what he had learned at school over the last couple years to help the public identify whether something has been written by a machine?

Tian already had the know-how and even the software on his laptop to create such a program. Ironically, this software, called GitHub Co-Pilot, is powered by GPT-3. With its assistance, Tian was able to create a new app within three days. It’s a testament to the power of this technology to make us more productive.

On January 2nd, Tian released his app GPTZero. It basically uses ChatGPT against itself, checking whether “there’s zero involvement or a lot of involvement” of the AI system in creating a given text.

When Tian went to bed that night, he didn’t expect much for his app. When he woke up, his phone had blown up. He saw countless texts and DMs from journalists, principals, teachers, you name it, from places as far away as France and Switzerland. His app, which is hosted by a free platform, became so popular it crashed. Excited by the popularity and purpose of his app, the hosting platform has since granted Tian the resources needed to scale the app’s services to a mass audience.

9 . Emma, my 11-year-old, has a serious letter-writing habit. She _______ actively with her favorite people. A letter from Emma is likely to include Mime art, a joke or two, and enough questions to guarantee a_______.

A few days ago, she wrote to our mail carrier Daren and expressed how_______ she was to him for taking her letters and_______ them Emma wrote, " You are very important to me because you make it possible for me to stay in touch with my friends since I don't have a phone. I make people happy with my _______ , but you do too."

The next day, Daren replied, expressing how _______ he was. Interestingly, letters _______ to Emma kept arriving. Daren had _______ Emma's note as a "Token （表示）of Thanks' in the internal US — post. Many postal folks wrote to thank her.

These letters are filled with family, hobbies, and a sense of kindness, and something more. People felt _______.“I work alone in a small rural post office…”“Few people think about how ________we work …”“I can't tell you how much it ________ to read your letter...”

We've all been in a moment of________isolation that is amplifying （放大）a real epidemic of loneliness, anxiety, and depression. Emma's ________to me was simple： It's the small things that________ most. Send a letter. Make a call. You can start the same goodness with the people that you ________ , respect, and love. Just tell them that you miss them, love them, or just see them.

10 . Individuals who believe their talents can be developed （through hard work, good strategies, and input from others） have a growth mindset （思维模式）.They tend to achieve more than those with a more fixed mindset （those who believe their talents are born）. This is because they worry less about looking smart and they put more energy into learning.     1     Let's take a look at three common misconceptions.

1. I already have it, and I always have. People often confuse a growth mindset with being flexible or open-minded or with having a positive outlook — qualities they believe they've simply always had. My colleagues and 1 call this a false growth mindset.     2     And that mixture continually evolves with experience. A “pure" growth mindset doesn't exist, which we have to acknowledge in order to attain the benefits we seek.

2. A growth mindset is just about praising and rewarding effort.     3     In both settings, outcomes matter. Unproductive effort is never a good thing. It's critical to reward not just effort but learning and progress, and to emphasize the processes that yield these things, such as seeking help from others, trying new strategies, and taking advantage of setbacks to move forward effectively.

3.    4     Mission statements are wonderful things. You can't argue with values like growth,

empowerment （赋能），or innovation. But what do they mean to employees if the company doesn't carry out policies that make them real and attainable?     5     Organizations that embody a growth mindset encourage appropriate risk-taking, knowing that some risks won't work out. They reward employees for important and useful lessons learned, even if a project does not meet its original goals.
