After I read Moonlighting with Einstein (about mnemonics), I wondered how throughout the ages, technologies shaped the way we think and structure thoughts. This closely relate to it. I assume a 100 years ago, academic had far larger memory capacity than the average peer in today's world. We kinda traded memory for higher CPU frequency (or maybe just decreased our memory, maybe our software is digressing). But this could explain why the chain of thought was so clear to never make a mistake? I wonder if there is a research on this fascinating topic.
