Apple Silicon chips have transformed attitudes toward ARM architecture, from being suitable mostly for power-efficient mobile devices to also capable of powering desktop processors which Intel behind.ARM CEO Rene Haas has now weighed-in on the DeepSeek controversy in a new interview, expressing his skepticism about one of of the key claims and voicing his expectation that Chinas AI chatbot will be banned in the US Why DeepSeek caused US tech stocks to fallDeepSeek caused shockwaves in AI circles when the company posted benchmarks indicating that its performance was comparable to the worlds best existing models. Experts quickly verified the claims, with concerns raised that China was seemingly able to achieve this at a fraction of the development cost of US models.That created the possibility that US AI companies could be significantly over-valued, and soon face a lot more competition. It was this fear which saw the stock prices of tech giants fall with Apple a notable exception.Key to concerns was Chinas claim to have developed its model with a fraction of the computing power of US models like ChatGPT, claiming that software optimisation compensated for much cheaper hardware.But Hass told the Financial Times that he doubts this claim.He says he does not believe the rumours that they did this on a shoestring budget...I think thats where people just over-indexed on maybe the worlds coming to an end.He argued that if it were true, wed have seen US AI companies announce that they were cutting their capital expenditure plans to take advantage of this more efficient approach. So far at least, that hasnt happened.Expects DeepSeek to be banned in the USHaas also thinks DeepSeek will be banned in the US, while emphasizing that he doesnt have any inside knowledge on this, but is simply drawing what he believes to be a logical conclusion.He does not predict a rosy future for DeepSeek, saying he thinks it will get shut down. Washington is scrambling on what to do with this thing. Think about it...if youre not going to allow a TikTok, why would you allow this?Weve already seen privacy and national security concerns raised, with multiple security flaws found in the iOS app.AI-powered research could cure cancerHaas went on to say that the company plans in future to sell its own chips, rather than just selling licenses to use the architecture, and that he believes AI holds the potential to revolutionize medical research. He mentions using AI on DNA and RNA research [] There is, he says, an opportunity to cure cancer in our lifetime. Its pretty real.Image: ARMAdd 9to5Mac to your Google News feed.
