What's the difference between the Korean-speaking foreigner in the first video and the Korean-speaking foreigners in the second?

ANSWER: The foreigner in the first video learned Korean pre-Internet, and the foreigners in the second learned it post-Internet. Also, when the foreigner in the first video learned Korean, Koreans had much lower expectations for Korean-speaking foreigners than they do today. In the 1980s, Koreans were often surprised when a foreigner spoke even a little Korean, but these days Korean-speaking foreigners in Korea are a dime a dozen, and their Korean is much more fluent than the Korean of the foreigners in the 1980s.
