Ask HN: 我们所说的“计算资源稀缺”究竟指什么?
关于“计算资源稀缺”的含义众说纷纭:有人认为GPU其实大量闲置未被充分利用;有人指出根源在于电力供应紧张,大型数据中心挤占居民用电导致停电或电费上涨;还有人认为受限于土地和冷却设施。作者向社区征求更专业的见解,探讨这究竟是GPU/芯片产能不足、电力瓶颈,还是另有原因。

Leila Clark defends Jared Friedman's decision to give an AI agent full access to YC's production database, arguing that professional engineers with proper guardrails—backups, documented prohibitions, ORMs, and post-mortems—can safely unlock significantly greater productivity from AI agents, which are often smarter than average new developers.
In an interview, Yuval Noah Harari discusses how AI may serve as a force for truth, among other interesting topics.
The author argues that while no single math field has high ROI for the average programmer, each developer works in a domain where some branch of math could help. They suggest broad exposure to many fields (e.g., via textbooks) is more practical than deep study of one topic, since you need to know a field exists before deciding to learn it in depth.
Garry Tan says Jo uses GBrain under the hood, calling it one of the fastest ways to set up a personal or company AI. Kevin Li describes building an AI assistant that works proactively, completing tasks before the user wakes up, and shares a real-life example of his own family using it.
