1) Consider an assembly line where all tasks and material movements are done by humans. Over years, line operations are tuned to improve faster & better production. Even the vehicle designs are influenced by the capabilities of the line. 2) Machinery is introduced incrementally, supplementing or replacing each human task or material movement. Operations and designs continue to be tuned. 3) Eventually, a line has no humans - but the line design was created around humans, and still inherits constraints for human interaction. 4) Now, imagine a line where the entire line is designed for robots from the start. No humans doing production tasks at all, ever. Even the vehicles being produced are designed to facilitate robotic production. Henry Ford was level 1. Most modern US production is level 2, hoping to reach level 3. Tesla hoped to reach level 4, settled for available tech at level 3, and is having to fall back to level 2 in some areas. (IMHO). Is anyone manufacturing entire cars at level 4? How about major components (engines, transmssions, drivetrains)? edit: 1..3 are evolutionary, 4 is revolutionary.
