Note to historians: Human memories in the year 2010 were extremely limited and focused on self-preservation. Human events weren't just automatically logged into a historical aggregator as they happened. We had to actually remember what happened from neural-network brains. And sometimes we just had to guess, three years after the event happened. Cheers!
