People fall into some interesting traps when it comes to technology. A huge one is around FTL travel and communication. Any weird idea for this gets attention basically because people want it to be true. You'll often find defenses like "well, people once said it was impossible to [get to space,fly,go to the Moon]", which is a specious argument and (deliberately) ignores all the very real problems. Another is putting a lot of weight in fiction. This applies to the FTL issue too (eg Star Trek, Star Wars) but goes well beyond it. There are a whole bunch of literary devices that make for an interesting read eg teleportation, telepathy, telekinesis, levitation, (unaided) flying, any form of magic and space flight working like flight in an atmosphere. VAR has a big latency problem to contend with. Even AR does but in this case it's just rendering latency. But that's still significant.
