A Deep Dive into Room-Temperature Superconductivity: The LK-99 Replication Controversy and Practical Applications | Yunqi Capital

A Deep Dive into Room-Temperature Superconductivity: The LK-99 Replication Controversy and Practical Applications | Yunqi Capital

On July 22, 2023, a South Korean research team published a paper on arXiv claiming the discovery of the world's first room-temperature, ambient-pressure superconductor: LK-99. The material reportedly reached its superconducting critical point at 127°C under normal atmospheric pressure, **meaning LK-99 could function as a superconducting material in virtually any environment on Earth**. Multiple laboratories around the world quickly moved to verify LK-99's superconductivity under ambient pressure and room-temperature conditions.

Vol.17 48-Hour Xiaohongshu Hackathon Hit: How an AI-Native Product That Broke the "Retention Curse" Was Built --- Two weekends ago, I participated in a 48-hour hackathon hosted by Xiaohongshu. Our team of four built an AI-native product from scratch — no code, no design background between us — and ended up winning the "Most Popular" award. The product? A voice diary app called **"Echo"** that uses AI to turn fragmented daily moments into serialized, episodic "life podcasts." Think *This American Life*, but starring you. What surprised me wasn't that we won. It was that people kept using it *after* the demo. Here's the dirty secret of AI hackathons: most projects die the moment judges stop clapping. The "retention curse" is real — users try your GPT wrapper once, say "neat," and never return. We broke that pattern. Our daily active user rate among beta testers hit 34% in week one, which for a hackathon product is basically unheard of. How? Three deliberate choices we made against hackathon orthodoxy. **First, we refused to build a chatbot.** The default AI product in 2024 is still "talk to a large language model." We explicitly rejected this. Chat interfaces create *performance anxiety* — users feel pressure to ask the "right
