He Got Us Talking to Alexa. Now He Wants to Kill Off AI Hallucinations
British tech pioneer William Tunstall-Pedoe wants to solve the biggest problem in artificial intelligence.
If it weren’t for Amazon, it’s entirely possible that instead of calling out to Alexa to change the music on our speakers, we might have been calling out to Evi instead. That’s because the tech we know today as Amazon’s smart assistant started out life with the name of Evi (pronounced ee-vee), as named by its original developer, William Tunstall-Pedoe.
The British entrepreneur and computer scientist was experimenting with artificial intelligence before most of us had even heard of it. Inspired by sci-fi, he «arrogantly» set out to create a way for humans to talk to computers way back in 2008, he said at SXSW London this week.
Arrogant or not, Tunstall-Pedoe’s efforts were so successful that Evi, which launched in 2012 around the same time as Apple’s Siri, was acquired by Amazon and he joined a team working on a top-secret voice assistant project. What resulted from that project was the tech we all know today as Alexa.
That original mission accomplished, Tunstall-Pedoe now has a new challenge in his sights: to kill off AI hallucinations, which he says makes the technology highly risky for all of us to use. Hallucinations are the inaccurate pieces of information and content that AI generates out of thin air. They are, said Tunstall-Pedoe, «an intrinsic problem» of the technology.
Through the experience he had with Alexa, he learned that people personify the technology and assume that when it’s speaking back to them it’s thinking the way we think. «What it’s doing is truly remarkable, but it’s doing something different from thinking,» said Tunstall-Pedoe. «That sets expectations… that what it’s telling you is true.»
Innumerable examples of AI generating nonsense show us that truth and accuracy are never guaranteed. Tunstall-Pedoe was concerned that the industry isn’t doing enough to tackle hallucinations, so formed his own company, Unlikely AI, to tackle what he views as a high-stakes problem.
Anytime we speak to an AI, there’s a chance that what it’s telling us is false, he said. «You can take that away into your life, take decisions on it, or you put it on the internet and it gets spread by others, [or] used to train future AIs to make the world a worse place.»
Some AI hallucinations have little impact, but in industries where the cost of getting things wrong — in medicine, law, finance and insurance, for example — inaccurately generated content can have severe consequences. These are the industries that Unlikely AI is targeting for now, said Tunstall-Pedoe
Unlikely AI uses a mix of deep tech and proprietary tech to ground outputs in logic, minimizing the risk of hallucinations, as well as to log the decision-making process of algorithms. This makes it possible for companies to understand where things have gone wrong, when they inevitably do.
Right now, AI can never be 100% accurate due to the underlying tech, said Tunstall-Pedoe. But advances currently happening in his own company and others like it mean that we’re moving towards a point where accuracy can be achieved.
For now, Unlikely AI is mainly being used by business customers, but eventually Tunstall-Pedoe believes it will be built into services and software all of us use. The change being brought about by AI, like any change, presents us with risks, he said. But overall he remains «biased towards optimism» that AI will be a net positive for society.

Google races to put Gemini at the center of Android before Apple’s AI reboot
Google is using its latest Android rollout to position Gemini as the AI layer across phones, Chrome, laptops and cars.
Google is using its latest Android rollout to make Gemini less of a chatbot and more of an operating layer across the phone, browser, car and laptop, just weeks before Apple is expected to show its own Gemini-powered Apple Intelligence reboot at WWDC.
Ahead of its Google I/O developer conference next week, the company previewed a number of Android updates, including AI-powered app automation, a smarter version of Chrome on Android, new tools for creators, a redesigned Android Auto experience, and a sweeping set of new security features.
Alphabet is counting on Gemini to help Google compete directly with OpenAI and Anthropic in the market for artificial intelligence models and services, while also serving as the AI backbone across its expansive portfolio of products, including Android. Meanwhile, Gemini is powering part of Apple’s new AI strategy, giving Google a role in the iPhone maker’s reset even as it races to prove its own version of personal AI on the phone is further along.
Sameer Samat, who oversees Google’s Android ecosystem, told CNBC that Google is rebuilding parts of Android around Gemini Intelligence to help users complete everyday tasks more easily.
“We’re transitioning from an operating system to an intelligence system,” he said.
As part of Tuesday’s announcements. Google said Gemini Intelligence will be able to move across apps, understand what’s on the screen and complete tasks that would normally require a user to jump between multiple services. That means Android is moving beyond the traditional assistant model, where users ask a question and get an answer, and acting more like an agent.
For instance, Google says Gemini can pull relevant information from Gmail, build shopping carts and book reservations. Samat gave the example of asking Gemini to look at the guest list for a barbecue, build a menu, add ingredients to an Instacart list and return for approval before checkout.
A big concern surrounding agentic AI involves software taking action on a user’s behalf without permissions. Samat said Gemini will come back to the user before completing a transaction, adding, “the human is always in the loop.”
Four months after announcing its Gemini deal with Google, Apple is under pressure to show a more capable version of Apple Intelligence, which has been a relative laggard on the market. Apple has long framed privacy, hardware integration and control of the user experience as its advantages.
Google’s Android push is designed to show it can bring AI deeper into the device experience while still giving users control over what Gemini can see, where it can act and when it needs confirmation.
The app automation features will roll out in waves, starting with the latest Samsung Galaxy and Google Pixel phones this summer, before expanding across more Android devices, including watches, cars, glasses and laptops later this year.
The company is also redesigning Android Auto around Gemini, turning the car into another major surface for its assistant. Android Auto is in more than 250 million cars, and Google says the new release includes its biggest maps update in a decade and Gemini-powered help with tasks like ordering dinner while driving.
Alphabet’s AI strategy has been embraced by Wall Street, which has pushed the company’s stock price up more than 140% in the past year, compared to Apple’s roughly 40% gain. Investors now want to see how Gemini can become more central to the products people use every day.

Waymo recalls 3,800 robotaxis after glitch allowed some vehicles to ‘drive into standing water’
Waymo issued a voluntary recall of about 3,800 of its robotaxis to fix software issues that could allow them to drive into flooded roadways.
Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Qualcomm tumbles 13% as semiconductor stocks retreat from historic AI-fueled surge
Semiconductor equities reversed sharply after a broad AI-driven advance, with Qualcomm suffering its worst day since 2020 amid inflation concerns and rising oil prices.
Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.
Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.
The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.
The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.
Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.
Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.
Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.
