This document outlines how technology becomes integrated into human nature through seven levels: 1) Envisioned - an idea is conceived; 2) Operational - proof of concept exists but not widely applied; 3) Applied - introduced to society but not yet accepted; 4) Accepted - widely used and perceived as normal; 5) Vital - so integrated we feel lost without it; 6) Invisible - seen as natural not technological; 7) Naturalized - fully integrated into unconscious nature. Examples discussed include writing, cooking, mobile phones. The document argues technology progresses through these levels with some getting stuck and others advancing to become invisible partners and fully naturalized.
