Why does Skynet create multiple Arnold Terminators?

I mean it does indeed make very little sense and is something they need to and hopefully explain at some point. If you know the resistance has figured out what a T-800 in human form looks like by now, why keep pumping out the Arnold Mold and change it to some new form?

T3 actually tried to answer this. Saying that the creator of the terminators modeled the T-800 after some war hero, Arnold. And supposedly Skynet only has that model to use since it's built into its system. That would make sense I guess.

It's doing what it was programmed to do, more or less and doesn't really take the fact that humans come in all shapes and sizes and races into account.

The tv show Sarah Conner Chronicles actually I think explained it. And of course features a female version of Arnold's terminator. So yeah Skynet pumped out different kinds of the Cyborg Terminator, not just Arnold. So technically it COULD have been any of those that John sent back in time. All things considered, the true culprit is T2.

T1 is not to blame. Arnolds model was sent back by skynet to kill sarah, that's all we knew. For whatever reason on the bloody fucking sun, John Conner himself chose the model that tried to kill his mother to send back in time to protect himself. Which makes no sense or he simply didn't know what the fuck the terminator originally looked like and mistakingly sent back the Arnold version without a damn clue it was the first one too.

T3 states that BECAUSE Skynet knows that John Conner grew up with the Arnold version, it personally chooses to create that model to hopefully catch Conner off guard. So all this is T2's fault really. The intense amount of Arnold Terminators is due to the fact that T2 happened and Skynet some how knows that Conner was buddies with the Arnold Version.

But still, phew it's a head trip to make sense of why they'd make so many Arnold versions. If they want to trick the resistence into thinking their machines are humans, making a fuck load of the same one doesn't make any sense at all...

Overall I'll stick with T3's explanation. Skynet simply doesn't have another mold to use. It's just using the model it was programmed to use and doesn't bother going through the process to make a new one or change it. Most likely I'm guessing they do it like comic books, basically all the super heros are interchangable, but they wear different clothes and have different hair half the time. So yeah, although we've never seen it, there is a black arnold, asian arnold, hispanic arnold, and a long hair, and beard version arnold terminator running around to mix it up. So skynet's not completely retarded about it.
