Here are excerpts from a longer interview (in Norwegian), in which ex-world (classical) champion Magnus Carlsen. For those hoping to see him back in the world championship cycle at some moment in the foreseeable future, well, you might not want to get your hopes up. Ok, but at least the quest for 2900 is still on, right? Er, maybe not.
It seems that his motivation sometimes spikes for this occasion or that, but after a couple of decades as a professional he seems to be finding most of his joy in life elsewhere. Hopefully he finds it, and can at some point come back to chess with full motivation, whether he pursues the title again or not.

I'm surprised that Carlsen doesn't say more about chess 960. He seems to think that the level of forcing opening prep has just made it too difficult to play against well prepared, unambitious opponents at classical time controls. His remedy is faster time controls, but why not chess 960?
I'm under the impression that the chess 960 world championship has been played at rapid or faster time controls. But why not play that with slower time controls, starting with an hour or two for computer free prep? The content would be incredibly rich, and to my mind much more interesting for us spectators than listening to the umpteenth repetition of discussions of whether the players are just trying to remember their prep on move 15.
