Milestone stage: deployment
partially-demonstrated
Photonic components and interconnect exist; broadly useful efficient optical arithmetic is a different threshold.
Completion criteria: Independent workloads demonstrate at least a threefold wall-plug energy reduction at comparable accuracy/throughput, including memory, conversion, control and host overhead. Optical data links alone do not qualify.

The coalition concerns co-packaged optical interconnect. Moving data optically is distinct from performing neural-network arithmetic optically or reducing complete-system electricity tenfold.
