➀ The semiconductor industry is moving towards defining specific application sockets for chiplets to ensure interoperability and market viability. ➁ Standardization efforts like UCIe and BoW have focused on interconnects, but the real challenge lies in the link layer and application-specific requirements. ➂ The concept of 'sockets' refers to concretely defined mechanical, electrical, and functional specifications for chiplets, which will guide the development of interoperable chiplets.
