"Warren's remarks are very meaningful to me because he's a hero to me," Bezos said at the Seattle event. "I read all his books."
Buffett's Berkshire Hathaway doesn't have much in common with Amazon. Berkshire tends to buy up big stakes in industrial, food and financial companies with easy-to-understand business models. He's explicitly stayed away from Internet businesses and has publicly acknowledged missing them.
However, Buffett and Bezos are closely linked in other ways. Amazon is the fourth-largest U.S. company by market capitalization with a value of $464 billion, and Berkshire is two spots behind at $407.4 billion. Berkshire is the most valuable non-tech company in the U.S.
Buffett is the third-richest person in the world with a net worth of $88 billion, and Bezos is fourth at $84 billion, according to the Bloomberg Billionaires Index.
In response to the questioner, Bezos said he looks for inventions that are going to be better for customers and that are going to be big.
"We don't need to make sure it works, but if it works can it be big?" he said.
Bezos was also asked why he's taking Berkshire's approach in not splitting Amazon's stock, which is now priced at close to $1,000.
Bezos said he has no plans to do it now, "but we do review that on a regular basis."
Amazon did split its stock three times in the late 1990s.

Warren Buffett, 86, likes continuity. He lives in the same home he bought in 1958 and he's been based in the same office building for more than 50 years.
"It's a different sort of place. ... We have 25 people in the office," he says of the small Berkshire Hathaway headquarters in Omaha, Nebraska. "And if you go back, it's the exact same 25. The exact same ones."
Here's just a sampling of what you'll find in the self-made billionaire's work space.
I said this because no one else would. But it's the truth.
There never was a real "Trump Trade." I'm sorry if this is like hearing there's no Santa Claus.
What we did have was a rockin' year end thanks to the certainty of an ended election, even if half the country didn't get what it wanted – what we did get was some finality. A close Hillary win with a non-conceding Trump would have been disastrous for the market. A decisive Hillary win would have been bullish and the decisive Trump win was bullish.
Investors care more about having something like this resolved and in the rear-view mirror than they do about the actual outcome. See: Brexit. Closure is important.
Brad Keywell is enjoying a repeat act. In the short period of time since he co-founded Chicago-based Uptake Technologies in July 2014, Keywell has seen his start-up reach a $2 billion valuation on the back of $146 million in funding, including $40 million from Revolution Growth, the venture firm of AOL co-founder Steve Case. It makes Uptake one of the fastest start-ups to ever reach $2 billion in value, along with Groupon, the daily deals company also based in Chicago, which Keywell co-founded in 2008.
The investment firm exited its holdings of 21st Century Fox Class A shares.
The conglomerate also reported a 72 million increase in holdings of Apple shares to 129.36 million at the end of the first quarter. CNBC previously reported that Berkshire bought more than 70 million shares of Apple in January.
Berkshire also reduced its holding in IBM. On May 4, Buffett told CNBC he sold off about a third of a roughly 81 million stake in the first and second quarters of this year.
The filing shows all equity holdings for the conglomerate through the end of the first quarter, which Buffett is required to file with the SEC 45 days later. Berkshire's equity portfolio is managed by Buffett, along with smaller portions managed by deputies Todd Combs and Ted Weschler.

Former Yankee great Alex Rodriguez had two dreams as a kid. He wanted to be a professional baseball player and a CEO.
"Ever since I was 10 years old, I sat on my father's lap [and said] I have two dreams: [One was] to be a Major League Baseball player, but that usually never happens, and two was to be a CEO," A-Rod told CNBC's "Squawk Box" on Monday.
Coming up on one year since his final game in August of 2016, Rodriguez is now working on that second goal as chief executive of A-Rod Corporation, a holding company for his various investments, which include real estate, property construction, and fitness.
Rodriguez made about $448 million during a standout career as a third baseman and shortstop. He was a three-time Most Valuable Player with a career batting average of .295 and 696 home runs.
But in his career, Rodriguez was also caught up in a performance-enhancing-drug scandal that resulted in an MLB suspension for the entire 2014 season for violations of the league's drug agreement and labor contract.
If you're looking for a simple plan to build your retirement savings, one of the world's most successful stock market investors has some clear advice.
And he suggests staying the course, despite market fluctuations. "Keep buying it through thick and thin, and especially through thin," the chairman and CEO of Berkshire Hathaway said with a laugh.
On Friday, stocks dipped on mixed economic data and poor results from major retailers. Buffett suggested investors should take gloomy news with a grain of salt, however.
"The temptation when you see bad headlines in newspapers is to say, well, maybe I should skip a year or something. Just keep buying," he said. "American business is going to do fine over time, so you know the investment universe is going to do very well."
As proof of the record of long term growth, the "Oracle of Omaha" remarked that the Dow Jones Industrial Average "went from 66 to 11,497 in one century," recalling the index's exact close at the end of 1999.
"And since that century has ended it's more or less doubled again," Buffett added. Last week, the Dow closed just shy of 21,000.
Berkshire Hathaway chairman and CEO Warren Buffett is an investing legend. But if he could choose to be remembered for one thing, he said, it wouldn't be for his mastery of investing or business.
He wants to be remembered for being a good teacher.
The issue came up during the 2017 Berkshire Hathaway annual meeting. First, Buffett and his longtime business partner Charlie Munger were asked about a memory from their first annual meeting, and Munger said: "My first memory — when Warren got on the subject and they asked him what he wanted said at his funeral, he said, 'I want them to all be saying, that's the oldest looking corpse I ever saw.'"
Buffett joked, "That may be the smartest thing I ever said," before sharing what he would actually like people to remember of him: "With me, it's pretty simple. I really like teaching. I've been doing it formally and, you could say, somewhat informally all my life, and I certainly had the greatest teachers you could imagine.
"So if somebody thought that I did a decent job at teaching, I'd feel very good about that."
There's a fundamental change happening with investors: They're putting everything into index funds, CNBC's Jim Cramer said Tuesday.
At the Berkshire Hathaway annual shareholder meeting on Saturday, Buffett told investors they should stick to using index funds, saying they are better off. Buffett offered a negative view of actively managed funds, citing high fees and bad results for investors.
"And Warren Buffett says just keep contributing to your 401(k), just keep buying the index fund. I'm not saying that that is a complacent thing. I'm saying that's become kind of the way people save," Cramer said.
Cramer made his comments on the day the CBOE volatility index (VIX), widely considered the best gauge of fear in the market, hit its lowest since December 2006.
An index fund is a type of mutual fund with a portfolio constructed to track the components of a market index.

Just a little thought experiment –
The last time the US stock market (S&P 500) registered a peak-to-trough decline of 20% was in October 2011. We had another bear market beneath the surface from 2014 through the mid-point of 2016, in which the median S&P 500 stock had lost 25% while small caps and international stocks fared much worse, but it didn't exactly
A lot has changed since the fall of 2011, both in terms of the drivers in the market as well as the attitudes of investors. It's been a new era. So I wonder how this new era will react to a bear market rearing its head.
