a16z’s investment thesis treats AI inference as a stable, recurring workload where tokens per watt matter more than flexibility. Its sharper claim is that production—not chip design alone—is the moat: memory, power, cooling, interconnects, supply chains, and reliable rack-scale delivery determine unit economics.a16z 的投资论点认为，AI 推理已成为稳定的持续性负载，竞争核心是每瓦生成的 token。真正壁垒不只在芯片设计，还包括内存、供电、散热、互连和规模化交付。
AI agents break a core endpoint-security assumption: actions can no longer be attributed to the person at the keyboard rather than software acting with that person’s authority. a16z’s Neo thesis reframes control around real-time identity, agent guardrails, and attribution at execution; it remains an investment claim.AI Agent 打破了端点安全的旧前提：系统不能再仅凭行为判断操作来自用户本人还是其授权的软件。a16z 的 Neo 投资论点把控制重点转向实时身份、Agent 护栏与执行归因。
“World model” now labels systems that predict very different parts of reality. The useful distinction is functional: state, observation, action, and transition each support different capabilities, so visual plausibility alone does not establish physical understanding.“世界模型”正被用来指代预测现实不同部分的系统。更有用的区分是它在状态、观察、动作与转移中承担什么功能；画面逼真并不等于理解物理世界。
