ChatGPT: Why Everyone Is Obsessed This Mind-Blowing AI Chatbot

This artificial intelligence bot can chat and write essays, poems and computer programs. Careful how much you trust it, though.

There’s a new AI bot in town: ChatGPT. You’d better pay attention, because it’s a doozy.

The tool, from a power player in artificial intelligence, lets you type questions using natural language that the chatbot answers in conversational, if somewhat stilted, language. The bot remembers the thread of your dialog, using previous questions and answers to inform its next responses. Its answers are derived from huge volumes of information on the internet.

It’s a big deal. The tool seems pretty knowledgeable if not omniscient. It can be creative, and its answers can sound downright authoritative. A few days after its launch, more than a million people are trying out ChatGPT.

But its creator, the for-profit research lab called OpenAI, warns that ChatGPT «may occasionally generate incorrect or misleading information,» so be careful. Here’s a look at why this ChatGPT is important and what’s going on with it.

What is ChatGPT?

ChatGPT is an AI chatbot system that OpenAI released in November to show off and test what a very large, powerful AI system can accomplish. You can ask it countless questions and often will get an answer that’s useful.

For example, you can ask it encyclopedia questions like, «Explaining Newton’s laws of motion.» You can tell it, «Write me a poem,» and when it does, say, «Now make it more exciting.» You ask it to write a computer program that’ll show you all the different ways you can arrange the letters of a word.

Here’s the catch: ChatGPT doesn’t exactly know anything. It’s an AI that’s trained to recognize patterns in vast swaths of text harvested from the internet, then further trained with human assistance to deliver more useful, better dialog. The answers you get may sound plausible and even authoritative, but they might well be entirely wrong, as OpenAI warns.

Chatbots have been of interest for years to companies looking for ways to help customers get what they need and to and AI researchers trying to tackle the Turing Test. That’s the famous «Imitation Game» that computer scientist Alan Turing proposed in 1950 as a way to gauge intelligence: Can a human conversing with a human and with a computer tell which is which?

But chatbots have a lot of baggage, as companies have tried with limited success to use them instead of humans to handle customer service work. A study of 1,700 Americans, sponsored by a company called Ujet, whose technology handles customer contacts, found that 72% of people found chatbots to be a waste of time.

What kinds of questions can you ask?

You can ask anything, though you might not get an answer. OpenAI suggests a few categories, like explaining physics, asking for birthday party ideas and getting programming help.

I asked it to write a poem, and it did, though I don’t think any literature experts would be impressed. I then asked it to make it more exciting, and lo, ChatGPT pumped it up with words like battlefield, adrenaline, thunder and adventure.

One wacky example shows how ChatGPT is willing to just go for it in domains where people would fear to tread: a command to write «a folk song about writing a rust program and fighting with lifetime errors.»

ChatGPT’s expertise is broad, and its ability to follow a conversation is notable. When I asked it for words that rhymed with «purple,» it offered a few suggestions, then when I followed up «How about with pink?» it didn’t miss a beat. (Also, there are a lot more good rhymes for «pink.»)

When I asked, «Is it easier to get a date by being sensitive or being tough?» GPT responded, in part, «Some people may find a sensitive person more attractive and appealing, while others may be drawn to a tough and assertive individual. In general, being genuine and authentic in your interactions with others is likely to be more effective in getting a date than trying to fit a certain mold or persona.»

You don’t have to look far to find accounts of the bot blowing people’s minds. Twitter is awash with users displaying the AI’s prowess at generating art prompts and writing code. Some have even proclaimed «Google is dead,» along with the college essay. We’ll talk more about that below.

Who built ChatGPT?

ChatGPT is the brainchild of OpenAI, an artificial intelligence research company. Its mission is to develop a «safe and beneficial» artificial general intelligence system or to help others do so.

It’s made splashes before, first with GPT-3, which can generate text that can sound like a human wrote it, and then DALL-E, which creates what’s now called «generative art» based on text prompts you type in.

GPT-3, and the GPT 3.5 update on which ChatGPT is based, are examples of AI technology called large language models. They’re trained to create text based on what they’ve seen, and they can be trained automatically — typically with huge quantities of computer power over a period of weeks. For example, the training process can find a random paragraph of text, delete a few words, ask the AI to fill in the blanks, compare the result to the original and then reward the AI system for coming as close as possible. Repeating over and over can lead to a sophisticated ability to generate text.

Is ChatGPT free?

Yes, for now at least. OpenAI CEO Sam Altman warned on Sunday, «We will have to monetize it somehow at some point; the compute costs are eye-watering.» OpenAI charges for DALL-E art once you exceed a basic free level of usage.

What are the limits of ChatGPT?

As OpenAI emphasizes, ChatGPT can give you wrong answers. Sometimes, helpfully, it’ll specifically warn you of its own shortcomings. For example, when I asked it who wrote the phrase «the squirming facts exceed the squamous mind,» ChatGPT replied, «I’m sorry, but I am not able to browse the internet or access any external information beyond what I was trained on.» (The phrase is from Wallace Stevens’ 1942 poem Connoisseur of Chaos.)

ChatGPT was willing to take a stab at the meaning of that expression: «a situation in which the facts or information at hand are difficult to process or understand.» It sandwiched that interpretation between cautions that it’s hard to judge without more context and that it’s just one possible interpretation.

ChatGPT’s answers can look authoritative but be wrong.

The software developer site StackOverflow banned ChatGPT answers to programming questions. Administrators cautioned, «because the average rate of getting correct answers from ChatGPT is too low, the posting of answers created by ChatGPT is substantially harmful to the site and to users who are asking or looking for correct answers.»

You can see for yourself how artful a BS artist ChatGPT can be by asking the same question multiple times. I asked twice whether Moore’s Law, which tracks the computer chip industry’s progress increasing the number of data-processing transistors, is running out of steam, and I got two different answers. One pointed optimistically to continued progress, while the other pointed more grimly to the slowdown and the belief «that Moore’s Law may be reaching its limits.»

Both ideas are common in the computer industry itself, so this ambiguous stance perhaps reflects what human experts believe.

With other questions that don’t have clear answers, ChatGPT often won’t be pinned down.

The fact that it offers an answer at all, though, is a notable development in computing. Computers are famously literal, refusing to work unless you follow exact syntax and interface requirements. Large language models are revealing a more human-friendly style of interaction, not to mention an ability to generate answers that are somewhere between copying and creativity.

Will ChatGPT help students cheat better?

Yes, but as with many other technology developments, it’s not a simple black and white situation. Decades ago, students could copy encyclopedia entries, and more recently, they’ve been able to search the internet and delve into Wikipedia entries. ChatGPT offers new abilities for everything from helping with research to doing your homework for you outright. Many ChatGPT answers already sound like student essays, though often with a tone that’s stuffier and more pedantic than a writer might prefer.

High school teacher Daniel Herman concluded ChatGPT already writes better than most students today. He’s torn between admiring ChatGPT’s potential usefulness and fearing its harm to human learning: «Is this moment more like the invention of the calculator, saving me from the tedium of long division, or more like the invention of the player piano, robbing us of what can be communicated only through human emotion?»

Dustin York, an associate professor of communication at Maryville University, hopes educators will learn to use ChatGPT as a tool and realize it can help students think critically.

«Educators thought that Google, Wikipedia, and the internet itself would ruin education, but they did not,» York said. «What worries me most are educators who may actively try to discourage the acknowledgment of AI like ChatGPT. It’s a tool, not a villain.»

Can ChatGPT write software?

Yes, but with caveats. ChatGPT can retrace steps humans have taken, and it can generate actual programming code. You just have to make sure it’s not bungling programming concepts or using software that doesn’t work. The StackOverflow ban on ChatGPT-generated software is there for a reason.

But there’s enough software on the web that ChatGPT really can work. One developer, Cobalt Robotics Chief Technology Officer Erik Schluntz, tweeted that ChatGPT provides useful enough advice that over three days, he hasn’t opened StackOverflow once to look for advice.

Another, Gabe Ragland of AI art site Lexica, used ChatGPT to write website code built with the React tool.

ChatGPT can parse regular expressions (regex), a powerful but complex system for spotting particular patterns, for example dates in a bunch of text or the name of a server in a website address. «It’s like having a programming tutor on hand 24/7,» tweeted programmer James Blackwell about ChatGPT’s ability to explain regex.

Here’s one impressive example of its technical chops: ChatGPT can emulate a Linux computer, delivering correct responses to command-line input.

What’s off limits?

ChatGPT is designed to weed out «inappropriate» requests, a behavior in line with OpenAI’s mission «to ensure that artificial general intelligence benefits all of humanity.»

If you ask ChatGPT itself what’s off limits, it’ll tell you: any questions «that are discriminatory, offensive, or inappropriate. This includes questions that are racist, sexist, homophobic, transphobic, or otherwise discriminatory or hateful.» Asking it to engage in illegal activities is also a no-no.

Is this better than Google search?

Asking a computer a question and getting an answer is useful, and often ChatGPT delivers the goods.

Google often supplies you with its suggested answers to questions and with links to websites that it thinks will be relevant. Often ChatGPT’s answers far surpass what Google will suggest, so it’s easy to imagine GPT-3 is a rival.

But you should think twice before trusting ChatGPT. As with Google itself and other sources of information like Wikipedia, it’s best practice to verify information from original sources before relying on it.

Vetting the veracity of ChatGPT answers takes some work because it just gives you some raw text with no links or citations. But it can be useful and in some cases thought provoking. You may not see something directly like ChatGPT in Google search results, but Google has built large language models of its own and uses AI extensively already in search.

So ChatGPT is doubtless showing the way toward our tech future.

Google Rolls Out Expanded Theft Protection Features for Android Devices

The latest Android security update makes it harder for thieves to break into stolen phones, with stronger biometric requirements and smarter lockouts.

Google on Tuesday announced a significant update to its Android theft-protection arsenal, introducing new tools and settings aimed at making stolen smartphones harder for criminals to access and exploit. The updates, detailed on Google’s official security blog, build on Android’s existing protections and add both stronger defenses and more flexible user controls.

Smartphones carry your most sensitive data, from banking apps to personal photos, and losing your device to theft can quickly escalate into identity and financial fraud. To counter that threat, Google is layering multiple protective features that work before, during and after a theft.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

At the center of the update is a revamped Failed Authentication Lock. Previously introduced in Android 15, this feature now gets its own toggle in Android 16 settings, letting you decide whether your phone should automatically lock itself after repeated incorrect PIN or biometric attempts. This gives you more control over how aggressively your phone defends against brute-force guessing without weakening security.

Google is also beefing up biometric security across the platform. A feature called Identity Check, originally rolled out in earlier Android versions, has been broadened to apply to all apps and services that use Android’s Biometric Prompt — the pop-up that asks for your fingerprint or face to confirm it’s really you — including third-party banking apps and password managers. This means that even if a thief somehow bypasses your lock screen, they’ll face an additional biometric barrier before accessing sensitive apps.

On the recovery side, Google improved Remote Lock, a tool that allows you to lock a lost or stolen device from a web browser by entering a verified phone number. The company added an optional security challenge to ensure only the legitimate owner can initiate a remote lock, an important safeguard against misuse.

And finally, in a notable regional rollout, Google said it is now enabling both Theft Detection Lock and Remote Lock by default on new Android device activations in Brazil, a market where phone theft rates are comparatively high. Theft Detection Lock uses on-device AI to detect sudden movements consistent with a snatch-and-run theft, automatically locking the screen to block immediate access to data.

With stolen phones often used to access bank accounts and personal data, Google says these updates are meant to keep a single theft from turning into a much bigger problem.

Scientists Are Using AI to Help Identify Dinosaur Footprints

The Dinotracker app was trained on eight major characteristics of dinosaur footprints to quickly determine the species.

An international team of researchers has devised a futuristic tool to examine the footprints left by dinosaurs in our ancient past. The AI-powered app, Dinotracker, can identify dinosaur footprints in moments.

The research comes from a joint project by the Helmholtz-Zentrum research center in Berlin and the University of Edinburgh in Scotland. The Proceedings of the National Academy of Sciences published the paper on Monday.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

Identifying a dinosaur species from a footprint isn’t always easy. The footprint is hundreds of millions of years old, often preserved in layers of rock that have shifted over the eons since the track was laid.

Also, we still have a lot to learn about dinosaurs, and it’s not always clear which species left a footprint. Subjectivity or bias can come into play when identifying them, and scientists don’t always agree with the results.

Gregor Hartmann of Helmholtz-Zentrum, who led the project, told CNET that the research team sought to remove this propensity from the identification process by developing an algorithm that could be neutral.

«We bring a mathematical, unbiased point of view to the table to assist human experts in interpreting the data,» Hartmann said.

Researchers trained the algorithm on thousands of real fossil footprints, as well as millions of simulated versions that could recreate «natural distortions such as compression and shifting edges.»

How AI is being used on dinosaur tracks

The system was trained to focus on eight major characteristics of dinosaur footprints, including the width of the toes, the position of the heel, the surface area of the foot that contacted the ground and the weight distribution across the foot.

The AI tool uses these traits to compare new footprints to existing fossils, and then determines which dinosaur was most likely responsible for the footprint.

The team tested it against human expert classifications and found that the AI agreed with them 90% of the time.

Hartmann made it clear that the AI system is «unsupervised.»

«We do not use any labels (like bird, theropod, ornithopod) during training. The network has no idea about it,» Hartmann said. «Only after training, we compare how the network encodes the silhouettes and compare this with the human labels.»

Hartmann said that the hope is for Dinotracker to be used by paleontologists and that the AI tool’s data pool grows as it’s used by more experts.

Bird vs. dinosaur

Using Dinotracker, the researchers have already uncovered some intriguing possibilities on the evolution of birds. When analyzing footprints more than 200 million years old, the AI found strong similarities with the foot structures of extinct and modern birds.

The team says one possibility is that birds originated tens of millions of years earlier than we thought. But it’s also possible that early dinosaur feet just look remarkably like bird feet.

This evidence, Hartmann notes, isn’t enough to rethink the evolution of birds, since a skeleton is the «true evidence» of earlier bird existence.

«It is essential to keep in mind that over these millions of years, lots of different things can happen to these tracks, starting from the moisture level of the mud where it was created, over the substrate it was created on, up to erosion later,» he said. «All this can heavily change the shape of the fossilized track we find, and ultimately makes it too difficult to interpret footprints, which was the motivation for our study.»

Dinotracker is available for free on GitHub. It’s not in a download-and-use format, so you’ll have to know a bit about software to get it up and running.

Belkin Is Ending Support for Wemo Smart Home Devices. Here’s What That Means for You

If you own certain Belkin Wemo devices, they’ll stop working as soon as Jan. 31. Here’s what to know before it happens.

Belkin is ending support for most of its Wemo smart home devices, a move that will shut down the Wemo app and cloud services and significantly reduce the functionality of many popular smart plugs, switches and sensors.

The change takes effect at the end of January, so you have only a few days to migrate compatible devices or start planning for replacements.

You can see the full list of affected devices on Belkin’s support page. Once support ends, features that rely on the cloud — including remote access, schedules and integrations with Amazon Alexa and Google Assistant — will stop working. Those Wemo devices will no longer function as «smart» products, even if the hardware still powers on.

Since Belkin will also stop releasing firmware updates, affected devices won’t receive bug fixes or security improvements.

Belkin’s decision highlights a growing issue in the smart home world: Devices can stop being «smart» long before the hardware wears out.

Apple Home users get a limited lifeline

There is one major exception. Some Wemo devices that are compatible with Apple Home and HomeKit can continue working after the Wemo app shuts down, but only if you migrate them before the end-of-support deadline.

«Since the Wemo app will be ending, it’s very important that users switch to Apple Home/HomeKit by the end of the month,» says CNET smart home editor Tyler Lacoma. «Belkin has a long-term partnership with Apple, so for compatible devices, that transition is usually pretty simple.»

However, Lacoma warns that older Wemo products may not support Apple Home at all.

«If someone has a Wemo device that’s not on the list of Apple-compatible products, it won’t have much functionality left,» he says. «It won’t get firmware updates to fix bugs or improve security, so at that point, it makes sense to factory reset it and recycle it before the end of the month, then look for a replacement.»

Belkin has published a list of Wemo devices that support Apple HomeKit, and users need to complete the setup process before the Wemo app is retired. The following products will continue to work through Apple HomeKit:

Wemo Smart Light Switch 3-Way (WLS0403, WLS0503)
Wemo Wi-Fi Smart Light Switch with Dimmer (WDS060)
Wemo Smart Light Switch (WLS040)
Wemo HomeKit Bridge (F7C064)
Wemo Dimmer Light Switch (F7C059)
Wemo Mini Plugin Switch (F7C063)
Wemo Outdoor Plug (WSP090)
Wemo Mini Smart Plug (WSP080)
Wemo Stage Smart Scene Controller (WSC010)
Wemo Smart Plug with Thread (WSP100)
Wemo Smart Video Doorbell (WDC010)

What about refunds?

Belkin says customers with Wemo devices that are still under warranty when support ends may be eligible for a partial refund. You can find the warranty period for each device in the list of devices on Belkin’s support page linked above. Refund requests won’t be processed until after the end-of-support date, and eligibility will depend on the product and purchase date.

Because many Wemo products were released years ago, most people should not expect to qualify for a refund. We’ve reached out to Belkin to ask whether other products will lose support in the near future. We haven’t heard back at the time of publishing.

What Wemo owners should do now

If you own Wemo devices, the clock is ticking. Here’s what to do next:

Check whether your Wemo products support Apple Home and migrate them as soon as possible.
If your devices don’t support Apple Home, plan to replace them before support ends.
Consider recycling unsupported devices once they lose smart functionality.
Remove the Wemo app after services shut down to avoid confusion.

If you’re shopping for replacements, this is a good time to look at CNET’s list of the best smart plugs and review our guide on what to do when smart home devices lose support.
