FORTUNE — It’s not often that billionaire investor Warren Buffett gets called out for being clueless.
But that’s essentially what venture capitalist Marc Andreessen did this week at a virtual currency conference when he said, in reference to Warren Buffett’s advice that investors stay away from Bitcoin, that “The historical track record of old white men crapping on new technology they don’t understand is at, I think, 100%.” Andreessen was responding to an appearance on CNBC where Buffett opined:
And yesterday Business Insider’s Henry Blodget entered the fray, defending Buffett’s skepticism of Bitcoin, saying it wasn’t based on ignorance of the technology as Andreessen asserts, but a healthy skepticism of all new technologies. To back up his argument, Blodget quoted at length from a Buffett-penned article, which appeared in Fortune in 1999. The article was written during the height of dotcom mania, as Buffett explained why he avoided investing in the flurry of new technologies that were then hitting the market. Wrote Buffett:
In other words, it’s not that Buffett is ignorant about technology. It’s just that he understands that it’s impossible to know which specific investments will benefit from a technology’s widespread adoption, even if you are prescient enough to know what technologies will revolutionize the world and how they will do so. Buffett chooses the examples of the car and aviation industries. Many people saw the revolutionary potential of these inventions, but such clairvoyance would be worthless to an investor if he chose the wrong car company. The same goes for aviation — which has notoriously been a difficult industry to profit from, despite its revolutionary effect on society.
And by this logic, Buffett is right to be skeptical of Bitcoin. Whether you hope to profit from the rise of cryptocurrencies by investing in Bitcoin itself, or companies that would profit from Bitcoin’s ascendence like the Andreessen-backed Coinbase, you’re going to need to know more than just the fact that cryptocurrencies will change the world to make money. After all, what if you buy a bunch of bitcoins, but it turns out that a bitcoin varient becomes the dominant form of virtual currency?
Adresseen, in an email interview with Forbes, called this analysis “unsophisticated.” Writes Andreessen:
The problem with this comeback is that Buffett isn’t trying to sound sophisticated or nuanced. Buffett’s very point is that a sophisticated or nuanced understanding of technology isn’t necessary — and is perhaps even detrimental — to making money on investments. Buffett’s style of investing requires very sophisticated knowledge of financials while avoiding understanding technology for fear that an emotional connection to the promise of that technology can take his eye off the ball of profits.
Essentially this disagreement can all be boiled down to the fact that Andreessen and Buffett are two different types of investors. Andreessen is a venture capital guy who makes his money by putting bets on countless long shots, and only needing to be right a fraction of the time. To know what long-shot bets you should make requires a deep knowledge of the technologies you’re investing in to aid you in your forecasting of how they will change the world. But even Andreessen knows he’s only going to be right a fraction of the time on an investment-by-investment basis. Buffett takes the complete opposite approach — by either investing in mature companies with very small and hard-to-perceive advantages over their competitors, or by leveraging his reputation and access to capital to make sure bets not available to anyone else (like the stake he took in Goldman Sachs at the height of the financial crisis).
In other words, both men are right. (And that’s why they have so much more money than you.)
