Tunneling PCIe over fiber is an interim step, at best. Once the industry gets serious about optical, I think they'll drop PCIe/CXL signalling and adopt a protocol better suited to the job. Maybe still use CXL-compatible semantics, but not the signalling.

I'm not sure i see the point of optical direct to the drive. I would expect optical PCIe links to a chassis with a backplane that breaks out to commodity drives.
