[Spaceships] Under what tech assumptions Space Fighters make sense?

[Celjabba]

No strong and trusted AI and reactionless drive are mostly imperative, yes.

Others assumptions :

-that no automatic system can work faster than the human brain+hand
(star war basic, mostly :
if even the -AA turret- have to be manned, it make sense to have fighters instead of homing misiles.
Galactica, also, this time by design : no AI/strong automatism mean immune to AI ennemy)

-A variant, FTL/weapons systems need a human mind to operate

-You have fighters that can operate for hours/days and have FTL travel/fast travel , but no FTL communication (or only ftl comm from fixed point to fixed point).
