对比真正「全能」，连微信收藏都能帮忙找的豆包手机助手（至少在被抵制之前），Gemini 目前的能力还相当局限，聚焦在打车、外卖、杂货这些日常场景，虽说底层技术能力更强，但用户的实机使用效果，跟鸿蒙的小艺、荣耀的 YOYO 等国产手机 AI 助手并无太大不同。，更多细节参见同城约会
A Riemannian metric on a smooth manifold \(M\) is a family of inner products \[g_p : T_pM \times T_pM \;\longrightarrow\; \mathbb{R}, \qquad p \in M,\] varying smoothly in \(p\), such that each \(g_p\) is symmetric and positive-definite. In local coordinates the metric is completely determined by its values on basis tangent vectors: \[g_{ij}(p) \;:=\; g_p\!\left(\frac{\partial}{\partial x^i}\bigg|_p,\; \frac{\partial}{\partial x^j}\bigg|_p\right), \qquad g_{ij} = g_{ji},\] with the matrix \((g_{ij}(p))\) positive-definite at every point. The length of a tangent vector \(v = \sum_i v^i \frac{\partial}{\partial x^i}\in T_pM\) is then \(\|v\|_g = \sqrt{\sum_{i,j} g_{ij}(p)\, v^i v^j}\).
