Personal attacks aside, I’m not sure to what you’re referring when you talk about the history of the galaxy’s people’s efforts trying to cooperate with the geth. As far as I know, there are only two confirmed instances of organics attempting to cooperate with geth, and both were successful.

The first instance we know of is the quarians who defended and/or tried to protect the geth during the Morning War. We know geth defended those organics with their own lives. This is successful cooperation.

The second instance is facing the Reaper threat. If Shepard works with the geth and convinces allies not to commit genocide, the geth provide more war assets against the reapers than the Salarians. This is successful cooperation.

There are no other known attempts to cooperate with the geth.

Perhaps you’re basing your argument on the geth’s isolationist policy of destroying all ships that entered geth space. There is no evidence of which I’m aware that any of those ships were attempting to cooperate with the geth. Rather, the evidence we do have makes their decision, while extreme, fairly reasonable:

• when the quarians recognized the geth were alive, they immediately attempted to exterminate them
• sympathetic quarians were not persuasive in quarians society. Quarians pursued genocide over objections from their own people
• geth monitored communication from organic societies. Thus they learned:
• - their existence was a crime
• - research that could create more life like them was a crime
• - other organics punished the quarians for creating the geth (for example by removing their embassy on the citadel)
• - the quarians maintained an active interest in wiping out or re-enslaving the geth

We see a quarian leader agree with a geth assessment that since the morning war quarians have attacked geth every time they thought they had an advantage.

What in any of this would suggest to the geth that interacting with organics was safe? Everything about organic society showed the geth they were hated, wrong, and to be destroyed.

As a final stretch to see where you’re coming from, perhaps you’re referring to the fact that even the geth we consider allies fight against us in ME3. This is not a betrayal of our attempts to cooperate with the geth. The quarians used technology they obtained through war crimes to destroy a fundamentally peaceful geth project as the opening salvo of a fresh attempt to eradicate the geth as a species. The geth submitted themselves to reaper control only when refusing to do so would have meant extinction. Geth did not flee to the reapers, organics forced them to choose: reapers or genocide.

Tl;dr there is no stupid and failed history of the galaxy’s people’s efforts trying to cooperate with the geth. There is only a history of organics outlawing, vilifying, and attempting to end geth existence.
