Agreed, he's confusing FTL travel, which has profound theoretical objections, with general interstellar space travel, which has no such issues, space rocks like Oumoumoua do it all the time. To a million-year-old, immortal alien ET, a journey of a hundred or a thousand years is trivial. An absolute paucity of imagination here.
Impressive, with all sorts of startling, interesting other potential applications, from generating intranet documentation to shared to filling in skeletal, fandom-type wikis and certainly many others.
