与此同时,信息本身也在不断贬值。2025年5月,Graphite研究团队发现,互联网上已有超过一半的内容,是由AI生成的。AI可以基于现有信息进行无限的重组和分发,使信息密度迅速上升,但它却很难提升信息的质量,反而令传播环境变得嘈杂——人们的注意力被更多消耗,也需要更多判断力来防止被虚假和垃圾信息淹没。

For the Poincaré half-space model in dimension 2, the metric evaluates on the coordinate tangent vectors \(\frac{\partial}{\partial x}, \frac{\partial}{\partial y} \in T_pM\) as \[g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\;\frac{\partial}{\partial x^j}\bigg|_p\right) = \frac{1}{y^2}\,\delta_{ij},\] i.e. the coordinate tangent vectors are orthogonal and each has length \(\frac{1}{y}\) — shrinking to zero as \(p\) approaches the boundary \(y\to 0\), which is what makes the space “infinitely large” near the boundary.
