And that might well be true, in whatever novel/game background you assume.

But Traveller and similar "classic" SF settings (including the latest Star Wars and Star Trek films) assume that humanity remains essentially unchanged in the future. Which means that individuals will need extensive special training in order to unthinkingly incorporate correct interpretations of multiple simultaneous perspectives into their reactions to situations during combat.

Particularly when their own precious hide is on the line, which condition would add all sorts of stress chemicals to their brain's evaluating mechanism. People who can remain calm under fire and handle their own natural limbs with confidence are rare enough. Someone who could simultaneously remotely control an entirely seperate device would be a truly exceptional individual.
