Just more evidence POET is very clearly on the right track with their PIC, this report prepared by DOE’s advanced scientific computing advisory committee (ASCAC), some good background on advancing systems post-Moore, and high performance computing systems roadmap to the 2030’s and beyond. Section 4.3 talks a bit about silicon photonics, looks very familiar:

Presentation at ASCAC meeting in September, looks at work being done at AIM photonics institute, once again systems and architecture looks to be right where POET has positioned themselves:
