A hot field these days is computer science, which studies intelligent software for big data and machine learning. For example, with deep learning, Google’s computer programs have recently defeated a professional 9 dan GO player. It seems that all fields ranging from biology and material to business and social sciences are hiring computer scientists as fast as they can. Is this enthusiasm a passing fad or a lasting phenomenon (at least long enough for your children)? It is a hard question to answer, especially if we notice the fact that computer science was hot at least twice before in the just past thirty years. In this presentation I will share some personal insights on this matter.
