Norwegian is surely a funny language ...
We all know how stodgy and uptight Magnus sometimes appears in his interviews, but it's a nice change seeing him talk in his mother language, where he's a lively and bright fellow, even at the age of 13. I certainly wouldn't have been able to be as equally level-headed as he was while facing Karpov. Whether he'll be the next WC? Most likely.
I find that highly unlikely.
There's a good YouTube video of Carlsen being interviewed on 60 MInutes. He sounded like a normal kid. Compared with the psychological train wreck that was Bobby Fischer, it was really quite refreshing.
Fischer definitely had two sides to him: the charming, quick-witted side that Cavett saw and then, on other occasions, his inner demons would find their way out and it was ""Fischer the looney tunes nutcase". After he won the World Championship in 1972, Fischer had nothing left to prove: he was the best, he knew he was the best, therefore a lot of incentive that he had to keep the demons in check evaporated. In 5 years after being at the top of the chess world, he was a homeless bum living on the streets of Los Angeles. And it didn't have to be this way. Fischer's lawyer had millions of dollars in endorsement contracts ready for him to sign that he simply walked away from. I wonder if he had second thoughts about that as he was sitting in that jail cell on that dark night. Probably not.
