Musk also took on Tesla short-sellers in a series of Twitter missives, saying on Friday that the "sheer magnitude of short carnage will be unreal".

Elon Musk has increased his stake in the electric vehicle maker he founded, a week after the Tesla CEO led a tense earnings call with Wall Street analysts.
Presented with Musk's comment, Buffett acknowledged that the acceleration of technological advancement in recent years has made more moats vulnerable and "susceptible to invasion". "Being the low-priced producer, for example, is a terribly important moat". Berkshire Hathaway owns See's sweets. Some of Berkshire Hathaway's other businesses also have moats wide enough to stave off competition from an innovative tech upstart, such as Garanimals, a line of children's clothing it owns, Buffett added.
Elon Musk also once excitedly explained that it was his goal to build a vehicle that would fly straight to Mars, and then he cleverly devised Starman. "Elon says a conventional moat is quaint, and that's true of a puddle of water". It's ridiculous, Warren does not intend to build an actual moat.

The two have also tweeted back in forth; almost two weeks ago he praised a Spotify play list of hers and she responded playfully.
