Well, it has been noted many times about the computer not producing survey ships, but they also don't seem to produce miners or are extremely inneficient with automating them. I feel totally comfortable trading mining techs to the computer because they don't use it at all. Every asteroid is at 5 and then the miner will move to a field 20 turns away rather than upgrade the one they are already on to 10.

Also, when asteroids flip to one of the AIs they do not later readjust the pathing when they get a world closer to the asteroids. I have many times come across a field sending 1 point of production to a world 1/5th of the map away whilst the world right beside the asteroid wallows in a productionless void.

I have also never seen an AI produce constructors to at least bring a resource to 34%, even though they have the tech to do so. That might just be a different priority.
