为什么 HN 推它
每当有人困惑「一根雷电线凭什么卖这么贵」时，HN 网友必推的工业级拆解视频，CT 透视对比一目了然。
「要是你好奇为什么雷电线比普通充电线贵这么多，前阵子有人拿工业 CT 扫过一根，去看看就明白了。」HN 网友原话：if you're interested in why the Thunderbolt cable costs more than charging cables, some folks put one through a CT scanner recently
英文原摘要（HackerTube / Claude 整理）
Adam Savage and engineer Zach Radding examine Lumafield CT scans of Apple's $130 Thunderbolt 4 cable alongside cheaper USB-C cables. They explain the internal components that distinguish Thunderbolt from ordinary USB-C.
Linked whenever people ask why a Thunderbolt cable costs so much; the CT scans show the construction difference clearly.
