Gary Marcus 质疑 Anthropic 高管关于 AI 资本开支推高全球 GDP 的说法
Gary Marcus 拆解了 Anthropic 高管那套"万亿资本开支等于 GDP 翻倍"的话术，教你识别这类话术套路。
Anthropic 的 Sholto Douglas 在访谈中称，超大规模云厂商今年 AI 相关资本开支约 1 万亿美元，若按每年 2 到 3 倍的增长趋势，2028 年可能达到 4 万亿美元，并在 2030 年代初开始让人类 GDP 翻倍。Gary Marcus 对此提出批评，认为这是科技行业常见的话术：把可信的资本开支增长与几乎不可能实现的 GDP 翻倍并列，暗示两者概率相当。Douglas 本人也在原话中承认这一概念"有点荒谬"，需要很多条件同时成立。
PSA: one of the most common rhetorical techniques in tech is to start with something very plausible (increase in capex to $4t) and go to something that has almost zero chance (doubling GDP in less than a decade), while pretending the two of our equal likelihood. don’t be fooled. Fireside Alpha @firesidealpha Anthropic's Sholto Douglas says AI capex could rise from $1 trillion this year to $4 trillion in 2028 and begin doubling humanity’s GDP by the early 2030s “Over the course of the last four or five years, we’ve been 2x-ing or 3x-ing the amount of compute capacity devoted to AI every year." "And so I think that’s roughly, together, the hyperscalers are spending about a trillion dollars this year on capex related to AI. A very interesting question will be, will that trend line hold, and so will it go to $2 trillion next year and then $4 trillion in 2028?" "And if that trend line broadly holds, and you can expand that to encompass the broader robotics industry, then that means that in the early 2030s, you start to get to the point where you’re actually effectively doubling the GDP of humanity, which, again, is a little bit of a ridiculous concept, but requires a lot of things to go right.” Your browser does not support the video tag. 🔗 View on Twitter 🔗 View Quoted Tweet 💬 5 🔄 1 ❤️ 13 👀 1448 📊 5 ⚡
