Though, getting to the moon didn't really give us anything (apart from seeing it as a valuable thing in itself).
> Apollo stimulated many areas of technology. The flight computer design used in both the lunar and command modules was, along with the Minuteman Missile System, the driving force behind early research into integrated circuits. Computer-controlled machining was first used in the fabrication of Apollo structural components.
