The YouTuber is not impressed with the billionaire's recent weird tweetstorm about starting a candy company and Musk's joking that we are living in a real life "Westworld", a reference to the HBO show about rebellious robots.
While Buffett said it did seem like more moats had become susceptible to invasion recently, he still observed plenty of companies, such as the See's sweets unit that Berkshire owns, where they were holding firm.
Elon Musk recently took aim at the idea a successful business needs a "moat" - a competitive advantage that keeps rivals at bay.
He followed up with another tweet: "Then I'm going to build a moat & fill it w candy". Yes, the same guy who is selling flamethrowers and has told his followers about this dragon-dreams, is now planning to open a Candy Company.
The jocular series concluded with a more serious critique of Buffett's moat theory.
While Buffett has long extolled the benefits of moats-which are a key component of his stock-picking process-Musk spurned the concept entirely during a Tesla earnings call this week. "It's ridiculous. Warren does not intend to build an actual moat".
Buffett responded over the weekend by saying that moats are still working for certain companies, despite technological advancements.
"Elon may turn things upside down in some areas".
Buffett said during Berkshire Hathaway's annual meeting on May 5 that Musk was wrong to think that defensive moats - the qualities that make a business appear hard to compete with - are "lame". It's hard to determine what his actual plans are, as Musk has proven to be quite unpredictable in the past.
However, while all that has been largely technology related, now Musk has taken interest in the food industry. Let's see how Musk creates Willy Wonka's chocolate factory in the coming years.
Musk was off and running after that and the first candy tweet was out. As always, if you have anything to share, feel free to sound them off in the comments section below!
