Elon Musk trolls Warren Buffett with tweets on candy company

Musk is “starting a candy company & it’s going to be amazing,” he said in a Twitter post Saturday. He was pushing back after Buffett and his business partner Charlie Munger said the Tesla Inc. founder was wrong to believe “moats are lame,” as Musk said in a conference call earlier this week. A moat is a business’s competitive advantage that keeps rivals at bay.
