Fast optical circuit switching to replace electrical packet switches in AI data centers
Electrical packet switching hits a hard wall at ~8 radix for 50 Tbps GPU links, forcing multi-tier switch fabrics that kill latency, power, and reliability. Nanosecond optical circuit switc…

Network becoming the primary bottleneck as GPU bandwidth outpaces electrical switching roadmaps
GPU/XPU egress bandwidth (50 Tbps and rising) is diverging from electrical switch roadmaps (200-400 Tbps chips), making the network the limiting factor for AI cluster scale. This shifts cap…

Optical switching slashes data center optics count, power, and failure rates by orders of magnitude
Keeping data as light through the switch fabric eliminates billions of optoelectronic converters, transceivers, and electrical switch ports. This directly reduces power draw, component coun…

European deep-tech founders must adopt US-style ambition and capital intensity to win global AI infrastructure races
European VC mindset of capital efficiency and incremental milestones fails in winner-take-all AI infrastructure markets where US competitors raise and deploy aggressively. Success requires…
