I suspect that tech-induced information overload will make traditional forms of intelligence and memory more rather than less important over time. This is because natural intelligence is far more nimble and creative than, say, a bureaucratic system of indexing, tagging, note-taking, mind-mapping, etc. Such systems have their uses, but in my experience, they can easily metastatize and become ends rather than means.
In other words, information overflow requires surfing, as opposed to the construction of big dams, canals and plumbing systems. š
