Actually I see flashcards differently. I cannot agree with the "everything Flashcards" idea, it does not work for me, and I can't imagine learning from cards.

With flashcards, I can create an interconnected map in my mind, it supercharges learning, provides structure, makes digesting new content much easier. That ready cache of information has proved immensely useful.

Using just the tools of logic and reasoning is incredibly slow, error prone and exhausting. Especially in a time constrained and pressure setting e.g. a production issue, a discussion with people having differing opinions, a test or an interview.

Flashcards take out a lot of friction from knowledge retention.
