Actually AIs will fight you back quite effectively the way the game now.
AI's must use the "Standard SE4" racial trait, and use their original AI without problems. They will (or at least they should) pick it when randomly added, and of course you should do it manually if you add them that way.

Of course that having AI that uses starwarish techs would be nice, but my priority right now is finishing all techs to get something more or less playable so we can multiplay.
