My Dad played the banjo, guitar, fiddle, harmonica and to some degree the piano. He taught me the banjo and fiddle. The guitar is easier than the banjo. The young kid in the video is very accomplished. Notice that he is playing the banjo the correct way by "picking" it and not strumming it. We went to a party last night and the fellow hosting it had his Grandson with him that had just received a guitar (a very nice one, in fact) for Christmas. I asked him if he knew how to play it and he said no. Within 45 minutes, I taught him three chords and he was playing Happy Birthday, which is a good song to learn with any instrument. BTW, he is 15 years old.
