Functionalism John Searle proposed a definition of "Strong AI" in 1980. "The appropriately programmed computer really is a mind, in the sense that computers given the right programs can be literally said to understand and have other cognitive states." He refined it over the years, and was, I think, eventually satisfied with equating it with functionalism - that is, the thesis that each and every mental state is constituted solely by its functional role. https://en.wikipedia.org/wiki/Functionalism_(philosophy_of_mind) #AI
