Computing Guru Criticizes ChatGPT AI Tech for Making Things Up

Vint Cerf, who helped create the internet’s core network technology, hopes engineers can improve artificial intelligence’s shortcoming.

Vint Cerf, one of the founding fathers of the internet, has some harsh words for the suddenly hot technology behind the ChatGPT AI chatbot: «Snake oil.»

Google’s internet evangelist wasn’t completely down on the artificial intelligence technology behind ChatGPT and Google’s own competing Bard, called a large language model. But, speaking Monday at Celesta Capital’s TechSurge Summit, he did warn about ethical issues of a technology that can generate plausible sounding but incorrect information even when trained on a foundation of factual material.

If an executive tried to get him to apply ChatGPT to some business problem, his response would be to call it snake oil, referring to bogus medicines that quacks sold in the 1800s, he said. Another ChatGPT metaphor involved kitchen appliances.

«It’s like a salad shooter — you know how the lettuce goes all over everywhere,» Cerf said. «The facts are all over everywhere, and it mixes them together because it doesn’t know any better.»

Cerf shared the 2004 Turing Award, the top prize in computing, for helping to develop the internet foundation called TCP/IP, which shuttles data from one computer to another by breaking it into small, individually addressed packets that can take different routes from source to destination. He’s not an AI researcher, but he’s a computing engineer who’d like to see his colleagues improve AI’s shortcomings.

OpenAI’s ChatGPT and competitors like Google’s Bard hold the potential to significantly transform our online lives by answering questions, drafting emails, summarizing presentations and performing many other tasks. Microsoft has begun building OpenAI’s language technology into its Bing search engine in a significant challenge to Google, but it uses its own index of the web to try to «ground» OpenAI’s flights of fancy with authoritative, trustworthy documents.

Cerf said he was surprised to learn that ChatGPT could fabricate bogus information from a factual foundation. «I asked it, ‘Write me a biography of Vint Cerf.’ It got a bunch of things wrong,» Cerf said. That’s when he learned the technology’s inner workings — that it uses statistical patterns spotted from huge amounts of training data to construct its response.

«It knows how to string a sentence together that’s grammatically likely to be correct,» but it has no true knowledge of what it’s saying, Cerf said. «We are a long way away from the self-awareness we want.»

OpenAI, which earlier in February launched a $20 per month plan to use ChatGPT, has been clear about about the technology’s shortcomings but aims to improve it through «continuous iteration.»

«ChatGPT sometimes writes plausible-sounding but incorrect or nonsensical answers. Fixing this issue is challenging,» the AI research lab said when it launched ChatGPT in November.

Cerf hopes for progress, too. «Engineers like me should be responsible for trying to find a way to tame some of these technologies so they are less likely to cause trouble,» he said.

Cerf’s comments stood in contrast to those of another Turing award winner at the conference, chip design pioneer and former Stanford President John Hennessy, who offered a more optimistic assessment of AI.

Google I/O 2025: How to Watch and What to Expect

With Android 16 out of the way, Google I/O will certainly be all about AI.

Google I/O 2025 takes place on May 20 and 21 with Google’s big keynote happening on day 1. We expect Big G to talk about its myriad innovations across its ever-expanding portfolio of products — almost certainly with a huge focus on AI every step of the way. If we collectively cross our fingers, promise to be good and eat all our vegetables then we may even be treated to a sneak peek at upcoming hardware.

Google also hosted a totally separate event that focused solely on Android. The Android Show: I/O Edition saw the wrappers come off Android 16, with insights into the new Material 3 Expressive interface, updates to security and a focus on Gemini and how it’ll work on a variety of other devices.

By breaking out Android news into its own virtual event, Google frees itself to spend more time during the I/O keynote to talk about Gemini, Deep Mind, Android XR and Project Astra. It’s going to be a jam-packed event, so here’s how you can watch I/O 2025 as it happens and what you can look forward to.

Google I/O: Where to watch

Google I/O proper kicks off with a keynote taking place on May 20, 10 a.m. PDT (1 p.m. EDT, 6 p.m. BST). It’ll almost certainly be available to stream online on Google’s own YouTube channel, although a holding video is yet to be available. There’s no live link on the I/O website yet, either, though you can use the handy links to add the event to your calendar of choice. Expect links to a livestream to be available closer to the day.

What to expect from Google I/O 2025

Little chat about Android 16: As Google gave Android 16 its own outing already, it’s likely that it won’t be mentioned all that much during I/O. In fact at last year’s event, Android was barely mentioned, while uses of the term «AI» went well over a hundred.

Android XR: Google didn’t talk much about Android XR during the Android show, focusing instead on the purely phone-based updates to the platform. We expected to hear more about the company’s latest foray into mixed-reality headsets in partnership with Samsung and its Project Moohan headset, so it’s possible that this is being saved for I/O proper.

Gemini: With Android being spun out into its own separate event, Google is evidently clearing the way for I/O to focus on everything else the company does. AI will continue to dominate the conversation at I/O, just as it did last year (though hopefully Google can make it more understandable) with updates to many of its AI platforms expected to be announced.

Gemini is expected to receive a variety of update announcements, including more information on its latest 2.5 Pro update which boasts various improvements to its reasoning abilities, and in particular to its helpfulness for coding applications. Expect lots of mentions of Google’s other AI-based products, too, including DeepMind, LearnLM and Project Astra. Let’s just hope Google has figured out how to make this information make any kind of sense.

Beyond AI, Google may talk about updates to its other products including GMail, Chrome and the Play Store, although whether these updates are big enough to be discussed during the keynote rather than as part of the developer-focused sessions following I/O’s opening remains to be seen.

You Can Now Buy Nike’s $900 Workout Shoes for Compression and Heating

The Nike Hyperboots, designed to help you warm up and recover from workouts, launched Saturday.

Those workout shoes with compression and heating that Nike and Hyperice showed off at CES 2025 earlier this year weren’t just a concept. The Hyperboot is now available to buy online in North America, so they’re within reach, as long as you’re willing to spend $899.

The high-tops, which Nike and Hyperice call a wearable much like your smartwatch, help your feet warm up before a workout, and then recover after it. The shoes do this with heating and air-compression massage technology, taking the idea of heating pads and compression socks and making them mobile.

«You can definitely feel the heat in here,» CNET former mobile senior writer Lisa Eadicicco said when she had the chance to try these workout shoes on in January. She walked across a demo room in Las Vegas wearing the fancy footwear to test out the compression and heating features.

The boots massage and compress your ankles and feet, and in CNET’s test, we could especially feel the heat around the ankles. Buttons on the shoes let you adjust compression and the amount of heat with multiple settings for each.

«The Hyperboot contains a system of dual-air bladders that deliver sequential compression patterns and are bonded to thermally efficient heating elements that evenly distribute heat throughout the shoe’s entire upper,» Nike said.

The battery lasts for 1 to 1.5 hours on max heat and compression settings, or 8 hours if you’re only using the massage setting. It takes 5 to 6 hours to charge via USB-C cable. The boots come in five sizes: S, M, L, XL and XXL.
