Was heißt hier "nur"?

Bei einer Wortlänge von 8 Zeichen und 10 Milliarden Menschen sind das immer noch 62500000 Wörter pro Mensch.

Mit Kompression hätte man die Datenmenge wohl noch um 98 % schrumpfen können. ;D

Interessant wäre es mal zu wissen, wieviele Dinge das menschliche Gehirn speichert, wenn man Wörter, Gedankengänge und sogar bildliche Vorstellungen in Daten umrechnet.
