1. A system for using artificially intelligent interactive memories, the system implemented at least in part on one or more computing devices, the system comprising: one or more processor circuits; a memory unit, coupled to the one or more processor circuits, that comprises a plurality of interconnected rounds of conversational exchange including a first round of conversational exchange, the first round of conversational exchange comprising a recording of a first conversation participant's first conversational activity correlated with a recording of a second conversation participant's first conversational activity; a picture-capturing device, coupled to the one or more processor circuits, configured to capture a stream of digital pictures of a user; and a sound-capturing device, coupled to the one or more processor circuits, configured to capture a stream of digital sound samples of the user, wherein the one or more processor circuits are configured to: detect the user's first conversational activity from at least one of the stream of digital pictures of the user or the stream of digital sound samples of the user; compare at least one portion of a recording of the user's first conversational activity with at least one portion of the recording of the first conversation participant's first conversational activity; determine at least a partial match between the recording of the user's first conversational activity and the recording of the first conversation participant's first conversational activity; and cause a display and a sound-producing device to play at least one portion of the recording of the second conversation participant's first conversational activity, the causing performed in response to the determining at least a partial match between the recording of the user's first conversational activity and the recording of the first conversation participant's first conversational activity.

The system of claim 1 , wherein the recording of the user's first conversational activity includes: a first sub-stream of the stream of digital pictures of the user, the first sub-stream of the stream of digital pictures of the user comprising the user's visual expressions or communication in a first part of a simulated conversation and a first sub-stream of the stream of digital sound samples of the user, the first sub-stream of the stream of digital sound samples of the user comprising the user's verbal expressions or communication in the first part of the simulated conversation.
