The bedbugs were smarter than the MBA
A nineteen-year-old Korean runaway is lying on a dining table in a Seoul bunkhouse, trying to sleep. The workers had already abandoned the floor because of bedbugs. They placed pots of water under the table legs, a moat strategy any medieval tactician would recognize. It worked for two nights. Then someone flipped on a light and saw the bugs crawling across the ceiling. They had scaled the walls, traversed the full length of the room overhead, and were dropping onto the sleeping men from above.
Chung Ju-yung, who would go on to build Hyundai into one of the largest conglomerates on earth, watched this happen and did not curse. He marveled. On the Founders podcast, David Senra was reading from Chung's autobiography and landed on the line that defined the man's entire operating philosophy: "Even bedbugs think long and hard and use every bit of energy they have to achieve their goal. And ultimately, they succeed. I'm no bedbug. I'm a man." Chung had already run away from his father's farm four times. The fourth was the last. He never went back to farming.
Most people who talk about persistence have never been genuinely desperate. They quote platitudes from climate-controlled offices. Chung's version was different because it came from a place where failure meant starvation, not a smaller bonus. He had watched his parents argue about food until the table was overturned and dinner ended up on the floor. The payoff from farming never equaled the labor. So he left, slept among insects, and decided those insects had more strategic patience than most people he'd met.
Felix Dennis, the British magazine magnate who built a fortune from nothing, arrived at a similar conclusion through entirely different circumstances. In How to Get Rich: One of the World's Greatest Entrepreneurs Shares His Secrets, Dennis argues that new or rapidly developing industries provide more opportunities to get rich than established sectors, for three reasons: availability of risk capital, ignorance, and the power of a rising tide. Chung discovered this intuitively. He moved from farming, where the ceiling was biological, into construction and shipping, where the ceiling was psychological. The constraint was never the industry. It was whether you could outlast the bedbugs.
Nine families by age nine
Toyoda Sakichi invented an auto-activated loom that would stop the moment a single warp thread broke or the weft thread ran out. One thread. Out of hundreds running simultaneously, the machine detected the one that failed and halted everything before a single centimeter of defective cloth could be produced. Taiichi Ohno, who built the Toyota Production System on Sakichi's principles, called this concept autonomation: automation with a human touch.
The brilliance was not the stopping. Any machine can be designed to stop. The brilliance was the conviction that producing defective output is worse than producing nothing at all. Most factories in the early twentieth century optimized for throughput. Keep the looms running. Patch the defects later. Sakichi reversed the priority. He decided the cost of a bad meter of fabric included every downstream minute wasted inspecting, recutting, and reselling it at a discount. The loom that stopped was cheaper than the loom that kept going.
Howard Marks, co-founder of Oaktree Capital, describes the same inversion applied to portfolios. The first principal element of investment defense, he writes, is the exclusion of losers. Not the selection of winners. Exclusion. Conducting extensive due diligence, demanding a low price, generous margin for error, and being less willing to bet on continued prosperity or rosy forecasts. Sakichi's loom and Marks's portfolio construction share a single operating assumption: the thing you don't produce matters more than the thing you do.
In The Keyboard That Beat a Better Keyboard: Path Dependence and the Carry Paid on Open Doors, the same logic appears from a different angle. Once a mediocre standard gets locked in, the cost of reversal compounds silently for decades. The defective thread keeps weaving itself into everything downstream. Sakichi understood that the only honest response to a detected flaw is a full stop. Not a committee meeting. Not a quarterly review. A stop. The organizations that struggle most are the ones that learned to tolerate small defects because stopping felt too expensive. It never is. The defect is always more expensive than the silence.
The fraud is the forecast
In 1864, a London stockbroker named Anthony Morse was leading a mining mania. Gold prices were climbing. The market was exuberant. Then Morse failed on April 18th, and mining stocks collapsed by an average of more than ninety percent. Edward Chancellor, the financial historian, recounts this episode in Devil Take the Hindmost and punctuates it with Mark Twain's line: "A mine is a hole in the ground with a liar standing next to it."
What stands out about this story is not the crash. Crashes happen on schedule, roughly once per decade, in forms just novel enough that the previous generation's scars offer no immunity. What stands out is the structure of the mania: rising commodity prices created a narrative, the narrative attracted speculators, speculators created a market, and the market validated the narrative. The loop fed itself until Morse's failure severed the circuit. Nobody saw the collapse coming because the forecast was the fraud. The rising prices were treated as evidence of value rather than evidence of crowding.
Anthony Scilipoti, a forensic accountant who has spent twenty-five years dissecting corporate financials, put it cleanly on The Knowledge Project podcast with Shane Parrish: "Being negative sounds intelligent because it focuses on facts and figures. Selling the positive side involves selling a dream." He paused and then added the line that matters: "None of these things matter until they matter. And then when they matter, they matter a lot."
The dangerous moment in any market is when the absence of bad news is mistaken for the presence of good news. Morse's investors weren't stupid. They were optimizing for a reality that hadn't yet updated. The stock certificates in their hands were priced as if the future had already been delivered. Mining shares in 1864 London. Golf club memberships in 1989 Tokyo, where joining a top country club cost $2.7 million and banks offered ninety-percent margin loans against the certificate. The asset changes. The architecture of the delusion does not. You can swap gold mines for golf memberships for AI compute without altering a single load-bearing wall. The forecast always sounds intelligent. That is precisely what makes it dangerous.
