Google's internal tests developing a censored search engine in China have been very promising, CEO Sundar Pichai said on stage on Monday as part of the WIRED 25 Summit. "It turns out we'll be able to serve well over 99 percent of the queries," that users request. What's more, "There are many, many areas where we would provide information better than what's available," such as searching for cancer treatments, Pichai said. "Today people either get fake cancer treatments or they actually get useful information." While onstage at the event, Pichai did not back away from Google's controversial decision to build a censored search engine in China.
