David Deutsch

David Deutsch is a theoretical physicist, the father of quantum computation, and has been described as “(the) philosopher of maximum freedom”. His work offers the best synthesis yet about deep ideas such as reality, science, personhood, AGI, knowledge, and progress. He has written two books: The Fabric of Reality (1997) and The Beginning of Infinity (2011). David can be found online at his website and Twitter / X.

AI Q&A (QRAG)

QRAG stands for Question Retrieval Augmented Generation. Focus on Foundations indexes questions and answers extracted from interviews, meetings, and books in a vector database. Semantic search finds relevant Q&A by meaning, rather than only by matching keywords, and returns quoted source passages with source links. The qrag-search skill retrieves those passages without generating an AI answer. The qrag-ask skill and web chat also give the retrieved passages to an AI model to synthesize an answer, with the direct quotes available for checking. Browse Transcripts to read the source material. An AI answer is a synthesis, not a verbatim statement by the original speaker. QRAG is open source. Point an AI agent to the public repository to ask questions about how it works, with explanations tailored to your background and interests.
