影片解說還是挺有料的，而且簡單易懂。Corning 的 Glass Bridge 光橋，不是一種新的光通訊技術。真正的問題，不在光，而在「光怎麼進入晶片」。以前資料中心裡，CPU、GPU 彼此之間主要靠銅線傳輸。但 AI 叢集越做越大，頻寬越拉越高，銅線開始遇到距離、功耗和訊號衰減的物理極限，所以光纖才會一路往晶片靠近，從機櫃外、機櫃內，慢慢走到今天的 CPO（Co-Packaged Optics）。但光纖再快，最後還是要把光送進光子晶片（PIC）。偏偏這最後一小段，也是最麻煩的一段。因為光不像電子訊號，可以靠金屬接點直接接上去。光纖和 PIC 之間必須做到微米等級的精密對準，通道越多，組裝越困難，良率越低，成本也跟著上升。很多人把它叫做「最後一公分」，其實不是因為距離真的只有一公分，而是整條光路最後、也是最難處理的一段。Glass Bridge 想解的，就是這個問題。Corning 利用自己最擅長的特殊玻璃製程，在玻璃裡預先做好光波導（waveguide），讓光在玻璃裡先完成導引，再透過可拆卸的連接方式接到 PIC。原本每一條光纖都需要高精度對位，現在變成先把整個光路整合在玻璃裡，再

Maybe I’m missing something, so I’d genuinely like engineers to explain this.If a bridge is elevated and designed with proper drainage, why does this particular bridge in Lagos always get waterlogged whenever it rains? This is not the first time I am seeing videos of this same exact place whenever it gets flooded in Lagos. Shouldn’t the water naturally flow off the bridge through drainage outlets instead of pooling on the bridge itself? Or is this a blocked drains or a design issue?I’m genuinely
