Larry Page and Sergey Brin are stepping down as CEO and president, respectively, of Google parent company Alphabet. Google is facing increasing criticism and investigations from authorities in the U.S. and Europe about its privacy policies and nature of its many-legged business. That will now fall to Pichai to wrangle and push through — though Brin and Page, both 46, have noticeably backed out of the spotlight already. Last year, Google raised hackles in Congress by refusing to send Page or Pichai to a hearing on Russian manipulation of internet services to sway U.S. elections. Page and Brin, in announcing the news Tuesday, said the company has “evolved and matured” in the two decades since its founding.
