Two parallel optical benches in bright daylight, one showing a light beam simply connecting two chip mounts, the other showing a light beam passing through a distinct computing element, a clear physical divider between the two lanes caught being set into place

Two Different Things Both Get Called "Photonic Computing." Only One of Them Does Math With Light.

Optical interconnects, already shipping, move data between chips faster and cooler. Optical compute, still emerging, tries to do the actual arithmetic with light. Conflating the two overstates how far this technology has actually come.
