Ted Bundy murdered at least 30 women across 7 states. He drove them in a Volkswagen Beetle - same car, same smile, same routine. The FBI called him the most organized serial killer in American history. Netflix made a $30 million series. Zac Efron played him on screen. He was executed in Florida in 1989. His little brother Rich was 12 years old, rafting rivers with him on weekends, sitting in the back seat of that same Volkswagen, thinking his big brother had everything figured out. In the video below, Rich Bundy tells the story of the moment he realized Ted had sent him home early to go murder someone. They were at the airport. Rich was upset - Ted had cancelled their plans out of nowhere, no explanation. As they waited to board, Rich glanced over at his brother's face. Ted was staring into the distance. Horrified. Disgusted. By something only he could see. Rich didn't understand it then. He does now. Ted had been loading the Volkswagen with rope, handcuffs and a crowbar before their trips together. He would pick up young women on the same roads they drove. Rich was in the back seat for some of those drives without knowing what the bag in the trunk was for. Ted sent him home that day because he felt the urges coming and didn't want his little brother in the car when it happened. That one decision broke Rich completely. He spent decades sitting alone in a camper, sometimes not leaving for three days at a time. Can't hold a normal life together. Says he's gotten used to jimmying his way through existence. Ted protected him from one night. The knowledge of what that night was destroyed the rest of his life anyway. Was Rich Bundy a victim of his brother, or did surviving that family come at a price nobody could have paid?

Warren Buffett disowned his granddaughter in 2006, writing that he had never accepted her as his grandchild, legally or emotionally. Buffett has largely avoided publicly discussing what happened between them. In the video below, Nicole Buffett tells her side of the story. Nicole had grown up as part of the Buffett family after Warren’s son Peter adopted her. She visited Warren in Omaha, called him Grandpa, and Warren’s wife Susan even referred to Nicole as one of her “adored grandchildren.” But being the granddaughter of one of the richest men in the world never meant living like one. Warren paid for her education, but Nicole didn’t have access to his fortune. She worked with children at Family Human Services in San Francisco and built her own life while carrying one of the most famous surnames in American business. Then their relationship fell apart after Nicole appeared in The One Percent, a documentary about wealth inequality. She later received a letter from Buffett telling her that he had not emotionally or legally adopted her as a grandchild, and that the rest of his family had not adopted her as a niece or cousin either. One detail made the letter even more painful. Buffett signed it simply “Warren.” Nicole still had a card from only a year earlier signed “Grandpa.” One of the richest men in the world had spent years as her grandfather. Then a letter told her he no longer considered himself one. Do you think Buffett had the right to draw that line, or did he take it too far? Save the video to finish Nicole’s story later, and follow for more heartbreaking stories from behind the lives of the world’s most famous billionaires.

Steve Jobs literally predicted the iPhone, the Internet, AI and the next 50 years of technology in a single speech from 1983:

two gas stations across the street can't stop destroying their own margins ben polak, yale university, econ 159 game theory, lecture 1. then the baseline. quebec city, over 300 gas stations, margins averaging 5.64 cents per liter in the late 1990s, about 9 percent of the price. then the collapse. a price war starting january 2000 drove those margins from 5.64 cents to nearly zero, and it lasted almost a full year. then the reason nobody blinks first. pricing just 2 cents above a neighboring station could cost a station 36 percent of its volume. then the transfer. both stations do better holding price high together, but each is individually better off undercutting, so undercutting is what happens. watch the moment he calls undercutting 'bad for the firm, bad for industry profit.' the price war was never bad strategy. it was the dilemma working exactly as predicted.

A bbb credit rating is a coin that only remembers its last flip john tsitsiklis, mit 6.041sc, probabilistic systems analysis, lecture 16, markov chains. then the matrix. s&p's own data, 1981 to 1996, a bbb company stays bbb 82.49 percent of the time in one year. nothing further back matters. then the slide. 5.81 percent of bbb companies get downgraded within that year, to bb, b, or ccc. real risk, ignored by most bond buyers. then the default. outright default inside that year hits only 0.17 percent of bbb companies, 34 times rarer than a plain downgrade. then the transfer. a markov chain predicts next year from this year's grade alone. the real risk in a bbb bond is the slide, not the cliff. watch the moment he shows the next state depends only on where it stands now, not how it got there. the rating was never a cliff edge. it was always a slope, graded in percent per year.

Your revenue forecast runs on an equation that has zero exact solutions gilbert strang, mit 18.06 linear algebra, lecture 16, projection matrices and least squares. then the problem. three months of data, reaching 1, 2, 2. no straight line passes through all three, zero exact solutions exist. then the fix. solve the normal equations, 3c plus 6d equals 5, 6c plus 14d equals 11. answer, d is one half, c is two thirds, one best line. then the leftover. that line predicts 7 sixths, 5 thirds, 13 sixths. actual was 1, 2, 2. the miss never hits zero, only its smallest size. then the transfer. that equation, a transpose a times x equals a transpose b, runs every model forecasting revenue, pricing risk, or reading gps. watch the moment he calls this equation the most important one in statistics. the line was never going to hit every point. the math was how close it could still get.

In 2005 Bill Gates and Warren Buffett told 92 Nebraska students how they could legally live the rest of their lives without paying a dollar of income tax. Only students could ask. Neither man saw a question in advance. One lunch with Buffett sold for $19 million in 2022. Fifty-five minutes of him and Gates answering these students is free. That September Forbes ranked them first and second in America: Gates at $51 billion, Buffett at $40 billion. The video is Nebraska public television's cut of that afternoon at the University of Nebraska-Lincoln, Buffett's old school. Between jokes about Halo 2 and losing at ping-pong to a nine-year-old, they lay out six rules. The newspaper test. Before any decision, imagine a smart, unfriendly reporter writing it up for your family tomorrow. Anything close to the line is out. The blank calendar. Gates said one of his favorite lessons from Buffett was a calendar with almost nothing in it. You have to be good at saying no. No committees. Buffett said brilliant investment decisions never come out of a large committee. Poll enough people and you buy what everyone already owns. You are the asset. Getting comfortable with public speaking, he said, pays off for 50 or 60 years, and avoiding it costs you just as long. Omissions. His worst mistakes never hit a statement: about $10 billion in profits from deals he understood and skipped, or made too small. The unsold gain. Tax arrives when you sell. His version: hold the stock, borrow against it every year to live on, and let the estate pay off the loan. He said he could have done it for decades and called it very unfair. His 1989 letter to shareholders has the math. Double $1 twenty times, selling after each double at a 34 percent tax, and you end with about $25,250. Hold through all twenty doubles and sell once, and you keep about $692,000. Same returns. The only difference is when the tax gets paid. "They have really taken care of the rich." That is Buffett on the cuts that took capital gains and dividends to a 15 percent tax. Gates answered: "I go along with that wholeheartedly." Everyone in his office paid payroll tax on their first $90,000 plus income tax, and he said their rate was often the same as his, maybe higher. Every paycheck you get loses 7.65 percent before income tax starts. A stock that rises and stays unsold has paid nothing. Billionaires do not avoid income tax by earning less. They avoid it by selling less. Price the tax bill before you cash out your next winner.

Warren Buffett bought See's Candy in 1972 for $25 million cash customers would pay 30 cents more per pound and keep buying 30 cents across 16 million pounds adds $4.8 million in pretax profit
