It is quite natural for formalizers to generalize definitions and propositions because it can make their work much easier. Eighth , by its insistence upon formalization, the QED project will add to the body of explicitly formulated mathematics. There is mathematical knowledge that is neither taught in classes nor published in monographs. In formalization efforts, we must formalize everything, and that includes mathlore lemmas. Ninth , the QED project will help improve the low level of self-consciousness in mathematics.
Good mathematicians understand trends and connections in their field.
The QED project will enable mathematicians to analyze, perhaps statistically, the whole structure of the mathematics, to discover new trends, to forecast developments and so on.
