That's true as of now, but let's think one or two steps further: Do you really think a mature AGI's (say with 3-6 year-old human intelligence) KB can reside in RAM, entirely? > Next, I suspect that whatever "bundling" you're talking about is likely to > be along "field" boundaries and is likely going to be akin to just reading > an entire FIELD table into memory (that will have the exact same structure > as all other field tables but will be contiguous on disk so as to promote > fast loads). To clarify what I mean: 1. the DB contains a large number of facts / rules (perhaps stored as "rows" in SQL parlance) 2. many of these rows have to be fetched for inference (Resolution tests if a rule leads to a successful proof, but more often than not the rules are discarded). 3. the rows are scattered all around the DB For example, let say I want to infer something about "Harry Porter" and "JK Rowling", I would want to fetch these facts / rules: 1. Harry Porter is a successful book series 2. Harry Porter belongs to the fantasy genre 3. JK Rowling is the author of Harry Porter 4. JK Rowling is now richer than Queen Elizabeth II. etc... But I would probably NOT need facts / rules like: 1. Einstein is the creator of General Relativity 2. Water is heavier than oil etc... So we should keep track of what rules are usually used *together*, and perhaps bring them into physically contagious storage. I'm not sure which DB feature(s) allow this...
