He describes it as safer, since gear usually ensures that someone will not be exposed to a certain conditon in a inhabitable environment for humans. He further argues that modern computers are more fragile in extreme conditions, and are not as strong as mechanical computers. He strongly supports it by comparing it to other popular technologies, "...imagine exposing a cell phone or tablet to acid or heat capable of melting tin" (Paragraph 7). He explains in comparison, that systems using mechanical parts are far more resistant to pressure, heat, and other forces, unlike modern technology.
