Typically in sci-fi, this is where technology is insanely inconsistent. Examples:
- In The Matrix, the characters are capable of inserting themselves into a perfect virtual-reality world from a distance; but they are incapable of controlling their robot-suits weaponry by remote control, but must man them directly, leaving them vulnerable to the robots.
- Avatar has similar inconsistency: i.e. they are capable of projecting life humans into the bodies of live Avatars, but can't remotely control attack-helicopters or attack-robot suits.
- In Star Wars, the ships wield rather primitive lasers and rocket-engines, but also have antigravity technology and hyperdrive technology that seems thousands of years more advanced.
