[Terminator] Why didn’t Skynet use chemical/biological weapons against humanity or bide its time to cause a recession then launch an attack.

There are few theories.

1. Skynet, as an AI designed for war, doesn't want to completely wipe out humanity, instead it seeks to create an enemy and fight a perpetual war.

2. Skynet, being a military AI, has some hard coded limitation on the kind of weapons it can use based on Geneva Protocol at the time of its programming. Nuclear, robotics, and conventional weapons are okay, while biological and chemical weapons are off limits.

3. Once humans have splintered into many, many isolated and hiding cells, biological weapons tend to not be all that effective. Skynet may also no longer have any viral samples. Although chemical weapons would have been very useful for human resistance that are hiding like rats though.
