This breakthrough isn't really anything that spectacular in my opinion. Sure they've integrated photonic communication with a standard CMOS process, but the advantage here is mainly bandwidth and power over existing processes. I imagine integrating Hybrid-Memory Cube or High-Bandwidth Memory with a processor die (2.5D or actual 3D) would likely give you higher bandwidth at lower TOTAL* power and lower latency. * In a lot of these photonics papers they conveniently forget to mention the power it takes to shine the lasers, and they only focus on the joules/bit number required in the communication. I suspect if you added up the entire power it would be higher overall than an electronic circuit.
