North and South Korea both developing ICBMs?

These days the global mainstream media are full of stories about North Korea's efforts to develop an intercontinental ballistic missile (ICBM) capable of delivering a nuclear warhead too the continental United States.  However, as noted in a recent article in The Korea Times, South Korea is also working on ICBMs, but of a different type.  The first time I recall hearing about this was in a speech given at an international conference in Daejeon by former KAIST president Sung Mo Kang.  He used the acronym ICBM to refer to Internet of things, cloud computing, big data and mobile technologies, just as The Korea Times article notes.
