but it was probably done because of the ease of SFX
Truly fantastic technology might look like a cheap visual effect. In Steven Gould's excellent, original
novel JUMPER (not the movie prequel titled JUMPER: GRIFFIN'S STORY), a young man learns that he has the ability to teleport. (Okay, so it's not technology, but you get the idea.) The book describes teleporting as instantaneous—Davy simply disappears or appears with no pop, no bang, no flash of light or other fireworks.
James Bond movies are closer to the source material than the movie JUMPER. In the movie, each jump is bounded by earthquake-like rumbling and shaking and the kind of "jump scar" seen from Nightcrawler in X-MEN 2. (Don't even get me started on everything else that is wrong with the movie and the differences from the book character.)
The point is, really advanced technology might not be terribly exciting visually. Seamless.
