The metric unit prefix ‘exa’ has existed since 1975 (it’s almost as old as I am) and yet - I had no idea it’s been there. Now I’m starting to see it… I guess I’ll be buying a 64 EB iPhone one day.

Please enlighten me - is yocto-technology already out there? 

Wikipedia lists other more or less known unit prefixes

BTW. I’m exa-excited about this.
