A wide-ranging interview with Apple CEO Tim Cook reveals him (kind of) denying OpenAI rumors; addressing the potential conflict between the power requirements of AI and Apples environmental goals; the journey toward Apple Glasses; and how Apples greatest legacy may be saving lives.Cook kicks off by denying that Apple was late to AI, pointing out that the company first built a neural engine into its products back in 2017 Apple wasnt late to AI, not considered charging for itCook spoke with Wireds Steven Levy.Back in 2017 we built a neural engine into our products. It was already apparent that AI and machine learning were huge. It became obvious that we had to divert lots of people to it, that it would be a new era for our products.Theres been talk of Apple potentially charging for some Apple Intelligence features in future, but Cook seems to essentially rule that out.We never talked about charging for it. We view it sort of like multitouch, which enabled the smartphone revolution and the modern tablet.Unclear denial of OpenAI rumorsBack in the summer, there were reports that Phil Schiller was going to join the board of ChatGPT creator OpenAI, in an observational role and then that he wouldnt. There was also talk of Apple investing in OpenAI.Cook denied this, though because both points were put to him in a single question, its not entirely clear what he was denying specifically.Q: First Apple was going to have an observer on OpenAIs board. Now youre not. Recently it was rumored you were going to participate in their big investment round. You didnt.A: Theres no truth behind that at all. And I would just say, our MO is not to go out and invest in a number of companies. Its rare that weve ever done that. So it would be odd, an exception, for us to do that there.Q: So you never considered investing in OpenAI?A: Im not going to say we never looked at it. Im just saying that it would be a rare move on our part to do that.AI energy usageLevy asked Cook whether there was a conflict between the extremely high energy demands of AI servers and the companys environmental goals.More challenges, yes. But are we coming off the goal? No, definitely not. With more data centers, you use more renewable energy, and weve built that muscle now. Since 2015 our carbon footprint is down over half, while our net sales have gone up well over 50 percent. I feel very good about 2030 [when Apple has said its entire supply-chain will be carbon-neutral].Levy pointed to Meta and Snap glasses, and asked whether that sort of form-factor was the end-goal for Vision Pro. Cook appeared to confirm that an Apple Glasses product is the long-term aim.Yes, its a progression over time in terms of what happens with form factors. AR is a huge deal. With Vision Pro, weve progressed to what is clearly the most advanced technology weve ever done, and I think the most advanced technology in the world in terms of electronics problems. Well see where it goes.Apples biggest legacy will be saving livesCook said that the companys biggest legacy was going to be in the health field, and noted the lives that had been saved through the companys work in this area.Its clear to me that if you zoom out way into the future, and you look back and ask what Apples biggest contribution was, it will be in the health area. Thats what I really believe. When we started pulling that string with the Apple Watch, it was a cascade of events. We started with something simple, like monitoring your heart rate, and then figured out we could pick up heart signals to get to an EKG and an AFib determination. Now we are monitoring sleep apnea. Ive gotten so many notes over time from people who would have not survived had it not been for the alert on their wrist.Much of the interview naturally repeats Cooks familiar talking points, but its still an interesting read.Image: 9to5Mac collage of photos by President.gov.ua/CC4.0 and Alexander GreyonUnsplashAdd 9to5Mac to your Google News feed.
