This chapter presents a short survey about the work that has been done on the Automath, is going on, and planned for the future. It also explains the concept of types and the matter of propositions as types and the survey is used to ventilate opinions and views in mathematics which are not easily set down in more technical reports. The project Automath develops a system of writing entire mathematical theories that verification of the correctness can be carried out by formal operations on the text. The motivations for the project: checking; understanding; and processing are discussed. These motives favor the choice of a system of a very general nature of formalizing mathematics of classical logic and set theory. One of the most important things in the project is that it expects machines to check the correctness of what humans have written. The machine has to find out whether there is a sequence of applications of the language rules that motivates the correctness of a line of the book.
