Elon Musk dreams big and tackles impossible problems. Warren Buffett and Charlie Munger are happy to aim lower: 'We don't want that much failure'

• Warren Buffett and Charlie Munger weighed in on Elon Musk at Berkshire Hathaway's annual meeting.
• The Tesla chief tackles complex problems, resulting in major wins and losses, they said.
• "We don't want that much failure," Munger said, explaining why they take fewer risks than Musk.

Elon Musk dreams bigger and tackles much more daunting problems than Warren Buffett and Charlie Munger, meaning he sometimes achieves great things but often falls short, the investing duo have said.
