Digital Materials
What	new lego bricks that are: 1. easy to assemble robotically 2. built strong structures and 3. have a fractal relationship in size so we can built high fidelity replicas.
Which	can functionalized components e.g., 3d circuits. strength goes up faster than linear with number of parts assembler can be cruder because parts self correct. can control structural properties and strength to weight. can build with fractal parts needing only log number of parts. assembler starts are serial then can become distributed assembler robots that are order size of parts not final object to be built
Why	legos are not scalable and strong enough.
