because it's been writing term papers for students. david pogue shows us how it works. >> reporter: i'm about to give you a software demo that i bet you'll never forget. it's artificial intelligence that writes for you. any kind of writing you like. write a limerick about the effect of artificial intelligence on humanity. >> there once was a.i. so grand it could help us with tasks at hand. but it also might do harm if its actions lack charm so, we must use it with care and command. >> now, i didn't want you to have to read a bunch of text off the screen, so i've asked voice artist keaton talmadge to read chat gpt's examples for us. hey, keaton. >> hi. >> thanks so much for doing this. >> of course. >> ready for the next one? >> let's do this. >> tell the goldilocks story in the style of the king james bible. >> and it came to pass in those days that a certain young damsel named goldilocks did wander into

the dwelling of three bears who were away from their home. >> reporter: it's called chat wclve welps chat gpt can write anything. letters, song lyrics, research papers, recipes, therapy sessions, poems, essays, outlines, even software code. within five days over a million people were using this thing. then microsoft announced it would build it right into microsoft word. and then the first books written by chat gpt have already been published. well, self-published. by people. >> i think this is huge. i wouldn't be surprised 50 years from now people look back and say wow, that was a really seminal set of inventions that happened in the early 2020s. >> reporter: eric brinelfson is a stanford professor and director of stanford's digital economy lab. >> most of the u.s. economy is

knowledge and information work, and that's who's going to be most squarely affected by this. i would put people like lawyers right at the top of the list. obviously a lot of copywriters. screenwriters. but i like to use the word affected, not replaced. because i think if done right it's not going to be a.i. replacing lawyers. it's going to be lyers w a.i.placin lawyers don't work >> rteutveryone is delighted. >> there's this thing called chat gpt. heard of it? >> no. i've been under a rock. so yeah, no. no idea. >> reporter: an a.i. researcher specializing in the ethics of a.i. >> i think we should be really terrified of this whole thing. >> reporter: chat gpt learned how to write by examining millions of pieces of writing on the internet. unfortunately, believe it or not, not everything on the internet is true. >> it wasn't taught to understand what is fact, what is fiction or anything like that.

it'll just sort of parrot back what was on the internet. >> reporter: and sure enough, it sometimes spits out writing that sounds authoritative and confident but is completely bogus. >> the first woman president of the united states, hillary rodham clinton, served as the 45th president of the united states from january 20th, 2017 to january 20th, 2025. >> reporter: and then there's the problem of deliberate misinformation. experts worry that people will use chat gpt to flood social wis letters that sound>> wuld unde harms before we proliferate something everywhere and mitigate those risks before we put something like this out there. >> reporter: but nobody may be more distressed than teachers. here's why. write an english class essay

about race in "to kill a mockingbird." >> in harper lee's "to kill a mockingbird quoenks the theme of vase heavily present throughout the novel. the story takes place in maycomb, alabama during the 1930s. >> reporter: some students are already using chat gpt to cheat. >> check this out. write me a 500 word essay proving that the earth is not flat. >> reporter: no wonder chat gpt has been called the end of high school english, the end of the college essay, and the return of the handwritten in-class essay. >> you don't need to know structure or syntax or vocabulary or grammar or spelling. >> the piece i also worry about, though, is the piece about thinking. >> reporter: jane rosenzweig is director of the writing center at harvard. >> when we teach writing, we're teaching people to explore an idea, to understand what other people have said about that idea and to figure out what they think about it. a machine can do the part where it puts ideas on paper, but it can't do the part where it puts your ideas on paper.

>> reporter: the seattle and new york city school systems have banned chat gpt. so have some colleges. >> the idea that we would ban it is up against something bigger than all of us, which is it's soon going to be everywhere. it's going be to be in word processing programs. it's going to be on every machine. >> reporter: some educators are trying to figure out how to work with chat gpt to let it generate the first draft. >> students will stop being writers and they will become editors. my initial reaction to that was are we doing this becaus chatgpt exists or are we doing this because it's better than other things that we've already done? >> reporter: open a.i. declined our requests for an interview but offered a statement. "we don't want chatgpt to be used for misleading purposes in schools or anywhere else. our policy states that when sharing content all users should clearly indicate that it is generated by a.i. in a way no

one could reasonably miss or misunderstand, and we're already developing a tool to help anyone identify text generated by chgp the talking abo an thmic watermark, an invisitag cntif ichatgpt ctors. but they probably won't stand a chance against the upcoming new version, chatgpt 4, which has been trained on 500 times as much data. people who've seen it say it's miraculous. >> a very senior person he basically described it as a phase change. it's like going from water to steam. it's just a whole other level of ability. >> reporter: like it or not, a.i. writing is here for good. stanford's eric brinelfson suggests we embrace it. >> i think we're going to have potentially the best decade of flourishing of creativity that we've ever had because a whole bunch of people, lots more people than before are going to

be able to contribute to our collective art and science. >> reporter: but maybe we should let chatgpt have the final word. i worry about chatgpt's effects on education, misinformation and jobs. >> chatgpt is a tool that can be used for a variety of purposes, both positive and negative. it is important for society as a whole to have ongoing conversations about the responsible development and deployment of a.i. technology. >> reporter: thank you. >> you're welcome. if you have any other questions or concerns, feel free to ask. >> that was david pogue reporting. the "overnight news" is back in two minutes.

>> reporter: the boat business at stacy stevens' marina in st. james city, florida went from recreational to recovery after hurricane ian crashed on shore in late september. >> it was heartbreaking to see like 15 years of building up a business to be wiped out in essentially i'd say even 24 hours where you know, one day it was good and then the next day it was completely gone. >> reporter: the only charter boat fishing being done is by cranes, fishing badly damaged boats out of the marina. these boats that are behind you, are any of them the boats that would regularly be in your marina? >> not one. >> reporter: many end up on stevens' marina, which has now become a boat emergency room, where they're stacked, cataloged and inspected by insurance companies. this new line of work has allowed her to remain open and keep her employees working. this giant sailboat just lifted on shore will be loaded onto a flatbed where the haul is carefully moved to a nearby field in what used to be stevens' palm tree nursery.
