Samsung's ambitions in services just took a bit of a blow. ZDNet has learned that Samsung's software research CTO Injong Rhee has left the company to become an "Enterpreneur in Residence" at Google. The 7-year veteran was important to the development of Samsung Pay and the company's Knox security platform. He also led the initial deployment of Samsung's in-house AI assistant, Bixby. Whatever you think of those products, he made them stand out -- no mean feat in a company better-known for its cutting-edge displays and processors than its software.
