If you're looking for an AI that compete with humans, you better go back to Chess. DW is way too complex for that. I find the game challenging, but it will always be through abritrary restrictions that this game can EVER be challenging. We are a very long ways from AI that can do what DWs AI needs to do, and do it the way a human would do it.
Please, don't tell me about AI in DW. It's very effective and in some situation you must think well about your tactics.
But implementing SoI makes more easily your win. I just asked to do it more complex, connect it harder with diplomacy, empire reputation and MAKE IT LOGICALLY. Declare war - colonize - make peace. Where is logic? Where are other possibilities?
I prefer something else, more complex, like this.
First scenario - colonizing on enemy territory - neighbor is angry, he declares war. Second scenario - colonizing on enemy territory - neighbor is angry, but we give him some compensation for exchange.
Third scenario - we buy colonizing rights - colonize planet lawfully - everybody happy.
So we have 3 scenarios instead 1. I think, it more interesting than we have now.
If it's too difficult, just add a button that turn SoI off.
