In the future, we might be able to zoom in from an impossible far off distance and see a target like some insane sniper. Daniel Taylor made this simulation that shows what an extreme 343x super ridiculous zoom would look like and it's crazy to imagine that this could be real.
In the future, they can always see you, basically. Taylor writes on how he made this simulation which was put together in After Effects:
A simulated camera zoom from 11mm - 3780mm using images shot at 11mm, 16mm, 50mm, 100mm, and 600mm.
