Without Elon Musk, do you think humanity would currently be in possession of reusable rocket boosters? (Regardless of Page and Brin's accomplishments.)

  Yes. The space shuttle had reusable boosters. Retro rockets for landings were used in th Apollo and Viking programs.

    Can you link to a specific rocket booster that was reused? Doesn't count if it's a retrorocket helping slow down some capsule that also has a parachute.
