There has to be the popcorn genre element, or I don't engage the same way. I like action and vehicle design and guns and computer graphics as much as I like allegory. It's a constant balancing game.

You can build a brain the size of a room, theoretically. You could also build a silicone based life form and it could be sentient. There's no limit to the height that you can reach in terms of design once we figure out how to design things, theoretically.

I was touching on the idea of the autonomous militaristic or autonomous law enforcement idea, but it wasn't the primary driving force.
