没错。这正是我向 @sama、@sundarpichai、@satyanadella 及西方 AI 领袖敲响警钟的原因：磷化铟(InP)衬底严重短缺/瓶颈将限制未来涉及光子学的 TPU/ASIC 部署。基于 InP 的收发器/激光器需求远超供应数倍（来源：LightCounting + 麦肯锡）。我们才刚开始 AI 扩张，TPU 相关的 InP 衬底行业已遇瓶颈 -> 被两家企业扼住咽喉：$AXTI、$SMTOY。若贸易战影响 $AXTI，AI 集群扩展将面临材料真空。这两家公司的重要性无与伦比，暂且不论股价。
Exactly. You just out why I'm sounding all the alarm bells to @sama, @sundarpichai, @satyanadella and Western AI leaders about huge InP substrate shortages/bottlenecks limiting future TPU/ASIC deployment involving photonics. Demand FAR exceeds supply for InP-based transceivers/lasers by multiple factors (source: LightCounting + McKinsey). We've only started the AI ramp with the TPU and the InP substrate industry is already bottlenecked -> held at chokepoint by two players: $AXTI, $SMTOY If trade wars affect $AXTI, there's just a complete void of available materials to scale AI clusters. There's just incredible importance on these two companies, stock price aside.
