They're talking a bit about languages, and the other fellow talks about his work as a professor and life in Canada, his family's heritage, etc.
Why don't we get people speaking multiple slavic or Indian or African languages? Actually we see quite a bit of multiple Germanic language videos. Steve and Luca spoke in English, German, and Swedish. Fasulye and Richard have a video with several Germanic languages, I believe. People learn romance languages because there are many native speakers of these countries (and for the natives of these countries, it is easy to learn the others).
