frontier AI companies can run more of the best AIs to speed up their own AI research, relative to their competitors. Right now these gains are maybe noticeable but not game-changing, but that'll probably change in the next few years.
这是整篇文章埋下的最深的炸弹：当顶尖 AI 公司开始用 AI 加速自身的 AI 研究，算力优势将产生复利效应——算力领先 → AI 研究更快 → 更好的模型 → 更快的研究 → 更大的算力领先。这个「飞轮」一旦转起来，计算差距将不再是线性的，而是指数级加速扩大。对所有「追赶者」而言，这是一个潜在的「逃逸临界点」。
