Tesla CEO Elon Musk once again suggested over the weekend that Warren Buffett made a mistake by ignoring the electric car pioneer's stock in his early years. On Saturday local time, X platform user George Mack shared an anecdote about the billionaire investor and praised Buffett's investment wisdom. Mark points out that in a 2001 speech, Buffett asked University of Georgia students two questions to help them better understand the personality traits they should adopt and avoid.


Mark said Buffett asked the students, if you could invest in a friend and receive 10% of his income for life, who would you choose?

Buffett then asked them which friend they would choose if they could bet their friends' earnings.

As Mark said in his post, the takeaway from these two questions is that the former group of friends possess character traits that should be adopted, while the latter group of friends possess character traits that should be avoided.

Musk also pointed out that Buffett’s thought experiment can be applied not only to money, but also to finding happiness and so on.

Musk responded to this post, but not to comment on Buffett's thought experiment, but to once again jokingly point out that Buffett should not miss the opportunity to invest in Tesla.

Musk said: "It's such a pity that he didn't invest in Tesla, when Tesla's market value was only 0.1% of today's value, haha."


In February this year, Musk tweeted that as early as 14 years ago when he had lunch with Charlie Munger, the latter had the option to invest in Tesla, which was valued at only about US$200 million at the time. Munger is a trusted long-term partner of Buffett and the vice chairman of Berkshire Hathaway.

Musk also tweeted at the end of March this year that Buffett could have invested in Tesla at a valuation of US$200 million, less than 0.1% of its current market value.

However, in response to Musk's remarks, Gary Black, former chief investment officer of Goldman Sachs Group and current managing partner of the Future Fund, once pointed out that Buffett would not hold Tesla shares because there is a huge difference between value investors and growth investors.

He wrote in a tweet at the time: "Investors need to realize the huge difference between value investors and growth investors. Buffett is a typical valueist. He will not own Tesla."
