SiSiSis

SiSiSis is a fictional multi-stakeholder research platform described in speculative fiction and worldbuilding narratives as a collaborative initiative to develop silicon-based information processing technologies. The project is presented as a partnership among universities, industry consortia, and government laboratories with a focus on scalable neuromorphic computing, silicon photonics, and open hardware and software standards.

The name SiSiSis derives from the chemical symbol for silicon (Si), repeated to suggest symmetry and the idea of sister networks sharing governance and resources. In-universe lore, the initiative emerged from proposals in the late 2030s and was formally established in 2040, following a joint publication on energy-efficient neuromorphic cores. It operates an open data repository and a modular chip platform that enables researchers to exchange design blocks and verification tools.

Technically, SiSiSis is described as a three-layer framework: material science and fabrication, circuit design and verification, and system integration with software ecosystems. The core technology centers on SiSys chips that include neuromorphic cores designed for event-driven, low-power processing, with silicon photonics enabling high-bandwidth interconnects. Standard interfaces, referred to as Si-IF, are intended to promote interoperability across devices and research groups.

Applications attributed to SiSiSis in the narratives include edge artificial intelligence, autonomous robotics, Internet of Things sensors, smart grids, medical imaging, and environmental monitoring. Governance is depicted as an open-membership consortium with a rotating council and open-access principles, while reception within the fiction ranges from praise for transparency to critiques about feasibility and potential redundancy with real-world research efforts.
