>The ATM is a bunch of inventions combined into one unit. One person saying they invented something so complex seems absurd. For the most part, that is how inventions work. The person who invented the mobile phone didn't invent radio transmission or integrated circuits. Most inventions involve putting together existing systems and inventions into a novel design. (As another comment points out, the Wright brothers is somewhat of an exception to this rule, as the did invent many of the features in their flying machine).
