I am really only asking if a concept of "direct knowledge transfer" or perhaps "downloads" exists as a point of discussion or study in philosophy and cognitive sciences.
In information theory, we have a well-defined physics for transferring enormous quantities of "information" across various media. But information with "meaning" or that can be characterized as "knowledge" moves extremely slowly across nervous systems and cannot be synthesized or directly combined.
Is there some area of study that defines and addresses this issue? Perhaps in attempts to "quantify" meaning or to "compute" directly through cells or to theorize what a direct mind-mind synthesis might mean? I suppose this is also another way of approaching old issues concerning limits of the "self."
