400 years is a bit pessimistic. Konstantin Tsiolkovsky, one of the key minds in rocketry, assumed that we wouldn't achieve orbit until the 21st century, let alone sending ships to the moon, or sending Voyager into interstellar space. I'd say we don't know, and to keep in mind that the future is always closer than we think.
