I don't like harvesters (no offence), their RP goes to pvp. They demand something what doesn't exist and there is not other way than kill or die. Good is that they are a few only.
But. I like the idea of robot house/civilization. It is year 817 and I am sure that robots can be wise like on. eg. Data (Star Trek). They can make their own civilization.
Another and important question is whether in the future we will remain human/biologic kind. The robot kind of human will be in the future for sure, so it should be in Disco. Some of them will be simply machines with program - looped loop in another loop, but other could know about their own existence.
I like Tinkerbell's idea about "fear of human oppression/attack". We humans don't like things which we don't understand. We hate the situation when something could be wiser than us. We don't like independent robots because of we are afraid of them.
I don't mean about hostility between Robot and Human kind, rather neutral/unfriendly. Robots could need some raw materials which are only in the human space, and robots could produce some goods/weapons/ships which humans want to get. Some factions could hate robots. Some factions could cooperate with them, House authorities could treat them suspicious, etc.
