Odds and Ends

Not exactly. Some house-building robots actually use bricks with those little nubs on the tops of lego bricks, with adhesive of course. The question becomes whether the robots should use those nubbed-bricks, regular bricks with regular mortar, or if it's all being done by robots anyway just 3D print the entire thing with layers of concrete.
Also, fun fact, in ancient times a lot of giant stone blocks did have those nubs on them to keep the blocks from slipping.
