Well, AI War is a game where a player can lose hours before realizing it. With 1100 AIP, the AI is fully aware of human threat and is actively allocating resources to their total destruction. I'm sorry for you three, but mankind is doomed because of your mistakes. Remember that at the beginning of each AI War game, mankind may live happy in deep space, surviving in spaceships, away from the AI. When the game begins, you (players/commanders) decide to go for an assassination campaign: using AI technology against itself before it realize you're trying to cut it out of your galaxy's sector.
Even with the spire campaign you are still playing an assassination game. By helping the aliens you're accepting to steer the AI faster for a better firepower, but the AI still has the resources to crush both humans and spire refugees. Your only chance of winning is by destroying the two sub-AIs managing your galactic sector before the central AI allows enough resources to kill you. Or by getting help from elsewhere, but shh!
Why doesn't the AI kill you from the beginning? Just because it has business to do somewhere else (minor spoiler: something else is requiring all it's military power in another galaxy). Yeah, I know, going on 120 planets for a large Spire empire is tempting. But AI War isn't about conquest. It's about assassination and survival.
TL;DR:
Sorry, pals. You lose hours earlier.
