[Starcraft] What's the point of sticking a squishy human in a mech suit?

I'm talking about the terran marines, it makes no sense to spend all those lifes and money/resources in not so effective frontline infantry.

A suit that has to provide life support to a human can't be as effective as a fully automated drone. Also, drones don't feel fear and can fight until they are destroyed.

The human soldiers only need a good shot at an arm or leg to be taken out of combat.


Human technology is advanced enough to install some automated factories that produce an endless stream of drones, making terrans the true masters of mass attacks.

Not even the zerg could compete when even a lowly zergling has two or three expendable drones going after it.

There are a few reasons

1. Many terran marines are simply conscripted prisoners being roided out on Stims so......who cares if "their" lives are wasted. It reduces the cost of prisons and thus is probably cheaper than making A.I.

2. Terran A.I. technology is not good enough or cheap enough. Humans can think for themselves and adapt at a moments notice. Rigid programing is actually really bad for something as chaotic as a battlefield.

3. Humans are plentiful, and cheap to reproduce.

4. Human soldier is more comforting to the mind than robot soldiers.  Even the prison scum conscripts are still human beings and thus at some level have human interests at heart.  Cold calculating robots might turn on all of humanity someday.
