Buffett's been right so many times in the past, been right about stock picks for so long, and where to invest, and what makes a good investment that it really is hard to argue against anything he says. He is the most successful investor of the 20th century and for good reason.
That all said, this is the 21st century, and even legends like Warren Buffett, see their time pass. He's what they call "Old Money". He along with others of his ilk like George Soros and Carl Icahn did it their way, with brilliant stock picks and positions, brilliant hedges, dealing with risk, holding onto winners, and cutting losers quick. They all grew up around the Great Depression and know the other side of the coin in dealing with adversity.
Now with this new era of Digital and Cryptocurrencies, their era is now coming to a close. They've all accumulated so much fiat during the 20th century, it really doesn't what the dollar does in the next decade or so before they pass. For the 21st century, if all goes as planned, these new innovators and investors will be new Buffetts and Soros and Icahns. It'll be the Vers, the Winkleviis, the Andresens, Voorhees, Drapers, and last but not least Nakamotos that'll be considered the brilliant financial minds of our time.
Long story short, yea Buffett's wrong.
