The building blocks: Artificial intelligence, software engineering, computer architecture, and very large-scale integration will play major roles: Artificial intelligence

There are two major branches of research in artificial intelligence (AI): intelligent machines and cognitive science. The first branch aims at the construction of computer programs that perform at high levels of competence in cognitive tasks, while the second is concerned with modeling human processing of information. The intelligent-machines branch is a computer science and engineering approach; it is not critical whether the methods mimic the internal structure of human behavior.
