Tim Cook's latest stop for his Asia tour is in Japan. Apart from riding the bullet train to travel around the country, Apple's CEO did an interview to share some interesting things about the company's plans for its Japan-based R&D center. Speaking with Nikkei Asian Review, Cook revealed that Apple's R&D facility in Yokohama, which is close to Japan's capital city Tokyo and is expected to be completed this December, will serve as the core of the tech giant's "deep engineering." Steve Jobs' successor admitted that he is remaining mum about what this is all about, but he did say that Apple is capitalizing on AI in cooperation with Japanese companies. Cook shared that they plan to make the most out of AI by crafting technologies that would be very useful, such as increasing battery life of certain products or recommending songs to Apple Music users.
