Microsoft chief executive Satya Nadella says he has been "humbled" in the aftermath of a gaffe in which he suggested women trust karma instead of asking for pay raises at a Microsoft press briefing in San Francisco, California. Even as Microsoft on October 20, 2014 ramped up Internet "cloud" offerings for businesses, its chief continued to be dogged by a comment that women should not ask for pay raises. Satya Nadella hosted an intimate press gathering in San Francisco, where the US software titan detailed its strategy and latest moves for helping businesses tap into the power of colossal online data centers as needed.
