The post expresses skepticism regarding the near-term viability of Co-Packaged Optics (CPO), citing yield issues at TSMC and a lack of confidence in CPO switches. The author suggests that Nvidia is signaling caution through the recategorization of revenue in its financial statements, while quoted reports indicate Nvidia may pivot to Near-Packaged Optics (NPO) due to yield failures on the Kyber mid-plane PCB. Overall sentiment is bearish for photonic bulls, suggesting that technical hurdles remain a significant barrier for these technologies.
