Addendum to Notes: The phrase "people of Earth" is a handy way to refer not only to homo sapiens, but also to pan troglodytes sapiens, gorilla gorilla sapiens, elephas maximus sapiens, loxodontus africanus sapiens, and numerous other former members of what is now politically incorrect to call the 'animal kingdom' who have been genetically "improved" to the point that they now have the right to vote (note the quotes). The term is mildly discriminatory since the trillion or so sophonts-of-Terran-stock are scattered through tens of thousands of star systems, but most folks will still know what you mean when you use it.
Addendum to Addendum to Note: It has just been pointed out to us that two classes of sophonts were omitted from the previous list -- human sub- (or super-, depending on who you're talking to at the time) species like homo sapiens purpureum, and artificial intelligences (er... 'people of machine ascent'). This illustrates nicely what happens when life is denied the cozy constraints of conventional evolution, while social concepts like political correctness are allowed to naturally evolve into the true monsters of the next millennium.
