What were the quarians supposed to do? Eventually the geth would have decided that they didn't need organics because they don't and would have attacked the quarians. The quarians knew it would happen so their only option was to attack first.
I'm not convinced by this line of reasoning. Assuming the geth decided they didn't need organics, why is it necessary to destroy them? Competition over sarcity of resources? Presumably their entire society was functioning just fine before the geth became sentient so this doesn't really make sense. Furthermore, the geth, being a collective individual, might not suffer from the effects of the Sarcity Principle that a society of individuals may operate under.
I think the quarians were more afraid of the geth being "WTF you enslaved us, we kill you". But this didn't happen, and the only reason the geth fought back was the basic instinctual drive anything with a brain stem has: self-preservation. By that time, the quarians were acting under fear and the geth probably calculated that the chances the quarians would forgive them and make peace equalled nil.
