From "Space Seed":
KHAN: Captain, although your abilities intrigue me, you are quite honestly inferior. Mentally, physically. In fact, I am surprised how little improvement there has been in human evolution. Oh, there has been technical advancement, but, how little man himself has changed. Yes, it appears we will do well in your century, Captain. Do you have any other questions?
KIRK: Thank you. They've all been answered.
I just wanted to add Khan's later quote from the briefing room scene--
KHAN: Nothing ever changes, except man.
What's Khan really trying to say?
Nothing really changes, except man, who changes very little, which is why Khan and the augments are going to rule the universe?
