Does it matter? Your genes and memes basically are who you are. They contain most of the necessary information to make you you

They are two important parts but there is a whole heap of important information stored in the brain that isn't 'memes'. Sentiments, desires, weightings, skills, habits, aversions. They just don't fit in under 'memes' - I mean whole parts of the brain don't even store memes at all.
