goal is I want to tell you about the state of the art in in circuit complexity lower bounds in what particular areas of certain complexity at least and the second goal is to give a general thought for a scientific audience so I'm I'm going to try to navigate these two things and hopefully it will turn out okay all right let's begin so as a young computer science theorist one is taught that there are roughly two kinds of people there are algorithms people and there are complexity people okay the algorithms designers asked the following very
