Re: "You just store samples"

Not necessarily. One can "summarize" the samples, as shown, to get approximations using much less data. And various sub-sets can be switched on and off as needed (or weights turned down).

Re: "BayesDB is a full implementation of what you've just described"

Perhaps, but using tools similar to what office workers currently use, staff without PhD's can study and adjust results based on direct observation and specialty sub-division. It's more about an approachable tool-set and division of labor than technical accuracy. It's about "de-esoteric-izing" AI so that more can assist in its tuning.

BayesDB provides a toolset, what you've proposed is where you need knowledge of the underlying process. You've shown some initiative here, but I'd really recommend studying what's out there and doing a true contrast of your solution to see the shortfalls.
