Being the Best Solver is Dead. The AI Era Belongs to the Best Problem Pickers.

For decades, the k-server conjecture was a mythical beast in theoretical computer science. Now, it’s solved—with an LLM standing beside the human researchers. The bottleneck in research is no longer your ability to execute the proof. It’s your taste. In the AI era, you no longer win by being the best solver; you win by having the courage to pursue problems worth solving.

Content Platforms Are Dead. AI Is the New Reader.

The quiet death of Baidu’s Baijiahao app marks the end of an era where platforms won by aggregating articles. AI has eliminated the content shortage, but the deeper disruption is that AI is now the reader’s front-end. If you create content, stop optimizing for algorithms and start building assets AI can’t summarize away: authentic human experience and trust.

Windows XP Lied To You About Your User Picture

For over two decades, we’ve looked back at the Windows XP user screen as a charming touch of early-2000s personalization. But we were all wrong. The system didn’t just grab a random picture. It ran a deterministic, collision-avoidance algorithm to ensure no two users on the same machine ever shared the same default image. It was a masterclass in pragmatic engineering.

The Algorithm Isn’t Misreading You. It’s Erasing You.

You’ve felt the eerie irritation of being misunderstood by a feed. But the problem isn’t bad engineering—it’s an epistemic trap. To know you, the algorithm must reduce your complex, contradictory human experience into a flat, trackable data point. The system’s success and failure are the exact same act.

Matching Algorithms Are a Lie. The Real Bottleneck in Group Travel Is Execution.

We think the hard part of group travel is finding the right people. It’s not. The real bottleneck is post-matching execution. Most social products fail by obsessing over soft preferences like MBTI, when the only thing that matters is verifying hard conditions and exposing the real-time cost of flaking. AI’s true value isn’t matching personalities; it’s acting as a shared-state tracker that forces cooperative equilibrium.

Your ‘Smart’ Prediction Bot Is Losing to a Coin Flip. Here’s Why You’re Still Making Money.

We build sophisticated prediction bots to parse data and find an edge. But when scored by the Brier metric, one Kalshi bot was actually worse than a coin flip. Profitability is a liar—it hides the fact that your ‘smart’ system is actively miscalibrated. Stop trusting P&L and start checking your math.

Your AI Doctor is a Racist Machine. Here’s the Danger.

Medical AI was supposed to be the great objective equalizer. Instead, it is automating historical bias. By confusing correlation with causation—using race as a proxy for complex social factors—AI entrenches race-based medicine, reducing patients to flawed data points rather than individuals needing personalized care.

Why.com Is Just a Side Project. Your Premium Domain Is Worthless.

When someone casually launches a side project on the premium domain Why.com, the internet’s first reaction isn’t awe—it’s confusion over why Reddit’s bots didn’t delete it. This absurd moment reveals a brutal truth for builders: your biggest obstacle isn’t branding or product quality. It’s getting past the algorithms that control who actually sees your work.
