In March 2016, AlphaGo, a Go program developed by Google DeepMind, surprised the world by winning four games of the historic five-game match against Lee Sedol, the world’s best human Go player. It was a chance to make the world realize potential of AI. AI is a core technology of the fourth industrial revolution, represented by IoT, big data, robots, etc. The technology is so important, because a technology level of AI will lead to the competitiveness of industrial technology of a nation. Against this backgrounds, the government strives to recognize the importance of AI, to support budget to develop studies, and to produce manpower in the national level of AI fields. This vitalization plan can be said to be very timely, because it meets the need of global trends, successfully fulfils the fourth industrial revolution, and targets to secure technology competitiveness as well as national wealth. However, the development and direction of national-level AI are pursued focusing on software based AI. And Korea seems to be a fast follower that follows the direction of advanced countries, narrowing the gap of technologies. It means that Korea cannot help but be a fast follower considering advanced economies, for example the U.S., and their R&D size and facilities in the software-based AI fields and strategies to attract excellent manpower and a number of researchers. Above all, in regard to the U.S., Google and facebook spend tremendous amount of R&D on AI, and the number of researchers in the U.S. far exceeds that of Korea.
