Google CEO Sundar Pichai talks with The Verge's Walt Mossberg about why Google thinks it can beat Apple, Amazon and Microsoft to make artificial intelligence easier and more helpful for every consumer. He says Google wants to offer smarter privacy controls, so that users might save certain types of conversations forever and wipe others off the record. Plus: Pichai adds that the company is investing more into its flagship Nexus devices for the Android operating system, but will not make its own smartphone without an OEM partner.
