Bootstrapping methods for productive nanosystems

Available methods for getting towards the necessary parallelity to produce macroscopic amounts of products

• bottom up: fully parallel (and hierarchical) self assembly of atomically precise chemically pre-produced building blocks
• top down: conventional photolithographic methods (MEMs)
• exponential assembly (the glue in the middle?)
• compact self replication (outdated)

---

• self emerging highly distributed self-replicative capabilities

Bottom up

There are at least three independent orthogonal axes where technological capability can be judged by and scaled along. These are:

• Convergent selfassembly levels
  (like experimentally demonstrated in SDN: bricks to blocks then blocks to multiblocks)
• Material stiffness
  (SDN, protein, stiffer stuff)
• Degree of introduction of positional assembly aspects
