I guess it's the difference between "I, a human, can travel between stars", or "We, the human race, can travel between stars". Sending off people to go colonise other systems, without ever knowing if they succeed or not (well, I guess they could send back a radio signal, but it would arrive thousands, if not millions of years later). I'm not sure that humans have the kind of longevity as a species needed for this.
