Biology solved nanotechnology billions of years ago, we’re just now beginning to notice. Every cell is a self assembling factory, a molecular computer, a repair system, and a power plant all at once, operating with precision we still can’t replicate. Proteins fold themselves into machines. Error correction runs nonstop. Nothing is wasted, everything is recycled. What we call "advanced nanotech" is mostly us rediscovering tricks life has been quietly using since the first cells appeared.
