In 2024 Professors Chan and Pak at UCLA and Rutgers proposed a case in enumerative combinatorics. At 16 years old, I used a custom GPT-5.5 harness to disprove this case. arxiv:2607.10084 1/3

Wealthy tech figures have come under fire from Democrats in recent years, with billionaires now facing potential wealth seizures in California. Many tech billionaires fleeing the Left, which is increasingly shaped by progressive attitudes, have appealed to the Right’s pro-capitalist sensibilities while failing to invest in right-wing causes or candidates. Investor Peter Thiel, recognizing the danger that socialism poses to Silicon Valley’s wealth, was an early investor in the Republican Party and Trump’s campaign, with Elon Musk later following suit. Zuckerberg and Chamath have drawn ire for the opposite reason. Both were late donors to Trump, supporting him only in 2024, and are now seeking relief from tax burdens after years of financing progressive causes. Many of the figures at the center of this political debate are members of the wealthy “PayPal Mafia” or are connected to Facebook, with considerable overlap between the two groups. The tech world has voiced growing fears that the Right may abandon or openly turn against it in retaliation for years of pro-woke opposition, even as it faces pressure from an increasingly hostile left flank animated by figures such as Mamdani.

A massive container ship crashed into the main bridge of Baltimore’s beltway this morning, causing total collapse to the bridge and cutting off the city’s container port from the global ocean. At least 6 people are missing. 🧵

My annual letter: danwang.co/2023-letter/ This year I discuss a walk-and-talk; Crumb; running and tangping; Knausgaard; Elon as Palmer Eldritch; quantity has a quality all its own; Chicago as a megacity; memelords; Norton; food as physical pleasure; hunching; and a pause.

95% of container ships that would’ve transited the Red Sea are now going around the Southern Tip of Africa as of this morning. The ships diverting from their ordinary course are marked orange on the @flexport map below.

At Teleport, we've created a new kind of ridesharing. You pay less for a ride. A lot less. And at the same time, your driver earns more. Much more. How? Here's how it works: Traditional ridesharing companies spend a lot on recruiting riders and drivers. This extra cost increases what you pay for a ride and reduces what your driver takes home. Our approach is different. With our approach, we spend almost nothing on recruiting. Instead, we use web3 rewards to motivate our current users to recruit new users. Lots of new users. The result? We save money. A lot of it. And we split those savings between you and your driver. You pay less for your ride. A lot less. And your driver takes home more. Much more. I'm writing to inspire you (yes you) to help us realize this vision. The sooner everyone knows what we've created, the sooner you'll be paying less for your rides and your driver will (finally) be getting paid their fair share. So, like and repost. Spread the word far and wide. Together, we will free the rideshare market once and for all. Carpe Viam.
