SpaceX's first crewed flight came nine years after the prediction, not three. Crew Dragon Demo-2 carried NASA astronauts Bob Behnken and Doug Hurley to the ISS on May 30, 2020 — six years past the promised ~2014 date, after Commercial Crew funding shortfalls, two Falcon 9 failure investigations, and Crew Dragon development setbacks.

Asked in April 2011 when SpaceX would put its first person in space, Musk answered 'in about three years' — implying roughly 2014. Dragon was then a cargo-only capsule that had flown once. The first crewed SpaceX flight, Demo-2, launched May 30, 2020, ending the post-Shuttle gap in American crewed launch but six years behind Musk's timeline.
