Earlier quoted context omitted.
This is not how I see it. Carlsen lost one insanely long online bullet match on lichess. He narrowly lost an online banter blitz match. This is not blitz, since also you have to talk while playing, which does not seem to suit Carlsen's personality. In classical, you can often "almost lose", except that Carlsen does not "actually lose", as exemplified by his ongoing record non-loss streak.
People are reading a bit too much into this loss. It is a big deal that someone was able to beat Magnus Carlsen at any time control, especially in this era where Magnus has seemingly reached a new level of chess skill, but bullet is by far the the easiest for a champion to make a mistake or series of them. Magnus is ridiculously strong at bullet but I’ve watched his live-streams and sometimes he blunders really badly…
