The Story of Titanium – by Brian Potter
But despite its abundance, it’s only recently that civilization has been able to use titanium as a metal (titanium dioxide has been in use somewhat longer as a paint pigment).

因为需要几千个分支机构统一部署，首先排除了英伟达，原因很简单，三家厂商都保证不了售后，以及将来是否断供，会不会提价。所以，英伟达的一切型号都不考虑。 三家厂商拿出的方案，软件不尽相同，核心算力方面，不约而同的选择了华为昇腾。 Source: 英伟达中国特供芯片遇冷，中国云计算大客户「看不上」性能降级版芯片，如何看待此事？ – 知乎
