Walmart may have paid more than $90 million after one of its trucks hit Tracy Morgan’s limo, court papers suggest. The crash killed his friend and mentor, James “Jimmy Mack” McNair.

The truck driver never went to prison.

In the video below, Tracy tells Matt Lauer why the money didn’t fix it: “Bones heal. The loss of my friend will never heal.”

On June 7, 2014, Morgan and his friends were riding home on the New Jersey Turnpike after a show in Delaware.

A Walmart truck slammed into their limo bus. Federal investigators said driver Kevin Roper was going about 20 mph over the limit. The lawsuit said he had been awake for more than 24 hours.

McNair died. Morgan was left in a coma. He learned his friend was dead two weeks later, after he woke up.

Walmart argued the injuries were caused partly because the passengers weren’t wearing seat belts.

In January 2015, McNair’s two children settled with Walmart for $10 million.

In May 2015, Morgan settled for an undisclosed sum. Days later he told Lauer, “The case is settled, but the pain is always going to be there.”

In November 2016, Roper pleaded guilty to vehicular homicide in a deal that let him avoid prison, according to published reports.

In 2017, court papers showed more than 90% of Walmart’s total payout went to Morgan and fellow comedian Ardie Fuqua.

Was a quiet settlement the right call, or should Morgan have taken Walmart to trial?

In 2009, BlackBerry sold almost 20% of the world’s smartphones, according to Gartner. By the end of 2016, its share was 0.0%, and the phone that helped push it out wasn’t even the first smartphone.

Apple never tried to be first.

In the video below, Tim Cook explains the rule behind the iPod, iPhone and iPad: “The philosophy has always been to be the best, not the first.”

He said it to Charlie Rose in September 2014, days after unveiling the iPhone 6.

“The iPod was not the first MP3 player,” Cook said. “It was arguably the best.”

When the iPhone launched in June 2007, BlackBerry and Palm were already selling smartphones. Cook calls the iPhone “the first modern smartphone.”

BlackBerry kept growing for about two years. In 2009, Gartner put its share at 19.9%. The iPhone had 14.4%.

Tablets had been on sale for a decade before the iPad. Cook says the iPad was the first to meet “any level of commercial success.”

In the iPhone’s first ten years, Counterpoint estimated, it brought in $775 billion in revenue.

In late 2016, BlackBerry shipped just 207,000 smartphones in a quarter.

The case for “best”: Apple let others take the risk, then took the market.

The case for “first”: BlackBerry and Palm built the category Apple sold into.

Would you rather be first to market, or the best one there?

In July 2011, the US was running a $1.3 trillion deficit, and Warren Buffett said he could end it in five minutes. His fix: every member of Congress loses the right to run again.

The deficit is still here. So is Congress.

In the video below, Buffett tells CNBC his plan in one sentence: “I can end the deficit in five minutes.”

On July 7, 2011, he spoke to Becky Quick in Sun Valley, Idaho. Washington was weeks away from an August 2 debt ceiling deadline.

His rule: any time the deficit tops 3% of GDP, “all sitting members of Congress are ineligible for re-election.”

“Now you’ve got the incentives in the right place,” he added.

That year, the deficit hit 8.7% of GDP, according to the CBO. Nearly three times his line.

By October, his words were spreading in a chain email. Berkshire said it was “not a serious proposal,” just a point about incentives.

In July 2023, the clip went viral again, and Elon Musk responded to it.

In fiscal 2025, the deficit was $1.8 trillion, about 5.9% of GDP, the CBO says.

The case for the rule: lawmakers would finally feel the cost of the deficit themselves.

The case against: the only people who could pass it are the ones it would fire.

Would you vote for Buffett’s rule, or is it a bad idea even if it works?

Elon Musk was worth $197.7 billion when Donald Trump, then facing a $454 million fraud judgment, came by his breakfast in March 2024. Two weeks later, Musk said on camera that Trump never asked him for money.

Then came the filings.

In the video below, Musk tells Don Lemon why he would not fund any candidate: “I don’t want to put a thumb on the scale monetarily.”

On March 3, 2024, Trump met Musk and several wealthy Republican donors in Palm Beach, The New York Times reported. The paper said Trump was urgently seeking a cash infusion.

On March 6, Musk posted: “I am not donating money to either candidate for US President.”

On March 18, the Lemon interview aired. Musk said he was at a friend’s place for breakfast. “Donald Trump came by. That’s it.”

Lemon asked about Trump’s legal bills. “I’m not paying his legal bills in any way, shape or form.”

Asked if he might donate after an endorsement, Musk said: “I think it’s unlikely.”

In May 2024, Musk launched America PAC.

In December, FEC filings showed he had spent at least $277 million backing Trump and other Republicans.

The case for Musk: in March he said he might endorse “in the final stretch” and that a lot could change.

The case against: in March he called a donation unlikely. By November he was the largest donor of the cycle.

Did Musk change his mind, or was the March answer never the whole truth?

Jeff Bezos makes about three decisions a day.

That is not an accident of schedule. It is the job description. As a senior executive, he told David Rubenstein, you are paid to make a small number of high-quality decisions, not a thousand mediocre ones.

The reason is energy. He schedules his hardest thinking for 10 a.m., and stops making decisions at 5 p.m. If a problem does not resolve by evening, it waits until tomorrow morning.

His other rule is less comfortable for people who like spreadsheets. He has said his best decisions in business and in life were made with heart, intuition and guts, not analysis. He adds a caveat that gets dropped: when analysis can settle a question, use it.

A man worth about $370 billion, and his most valuable asset is a protected morning.

Dario Amodei runs Anthropic, one of the labs building AI. his own forecast is that it disrupts 50 percent of entry-level white-collar jobs in 1 to 5 years.

in the clip below he answers what a kid finishing high school should do now.

"i'm concerned and i'm also hopeful" his worry is speed. people moved from farming to factories, then to knowledge work, and each time they adapted after a stretch of disruption.

this time one tool covers a wide range of knowledge work, so the first rung of several careers gets hit at once.

"it can do entry-level law work... it can do entry-level finance"
"we can't deny that it will also eliminate jobs... probably a large number of them"

his plan is to create jobs faster than AI destroys them. he admits there is no guarantee that works. his first piece of advice to a graduate is four words long.

so is learning AI at 18 enough to stay ahead of it - or is the entry-level rung already gone?

Andrej Karpathy built a working app in a few hours. then it took him another week to make it real.

in the clip below he explains why the code turned out to be the easy part.

this is his 40-minute keynote at Y Combinator's AI Startup School in San Francisco. he ran Autopilot AI at Tesla and helped start OpenAI.

the app is MenuGen. you snap a menu and it draws every dish. every new user gets $5 in free credits.

"this is a major cost center in my life"

the vibe coded demo ran on his laptop the same day.

then came login, payments, a domain and deployment. none of that was code, he says. it was him in a browser clicking around. adding Google login alone came with a wall of instructions.

software barely changed for 70 years, in his view, and then changed twice in the last few.

"remarkably we're now programming computers in English"

so is coding the easy part now - or did the hard part just move into the browser?

the S&P 500 bottomed at 676 in March 2009. in October 2026 it closed above 7,600. almost everyone who sold in the panic missed that.

in the clip below Buffett explains why panics feel the way they do.

fear and confidence don’t move at the same speed, he says. one hits everybody at once. the other comes back slowly, person by person.

“fear spreads instantaneously. confidence comes back through the door one at a time.”

there is no such thing as a mass return of confidence, he says. but fear can take over the whole market, and it will happen again.

then he is asked for his rule about investing. he gives the line he has repeated for decades.

“you want to be greedy when others are fearful and fearful when others are greedy.”

in October 2008, with markets in free fall, he wrote in the New York Times that he was buying US stocks with his own money.

easy to say on a stage - or the hardest rule in investing to actually follow?

Warren Buffett is 96. Bill Ackman says he once asked him about water at dinner and Buffett told him he hadn’t had any in 48 years.

in the clip below Ackman, the billionaire who runs Pershing Square, is asked what he would want to know from Buffett. his question is about health, not money.

how is it possible to stay that sharp drinking what Buffett drinks, he asks. Ackman has watched him sit on stage for eight hours at Berkshire meetings.

then the story. years ago Buffett came to his house for dinner. Ackman had Cherry Coke ordered online in advance, because he couldn’t find it in the supermarket.

at the table someone offered Buffett still or sparkling water. he said no thanks, the Coke was fine. Ackman asked if he ever drinks water.

“Bill, i haven’t had water in 48 years.”

Berkshire still holds 400 million Coca-Cola shares.
