Watching the game live with this open in another tab is cool. On Friday, it showed that Caruana had a winning position with a mate in around 30 moves. It was so non-intuitive that no chess player would have ever found it. But it is cool to see that the game "could have been" won.

True – yet extremely hard to find especially in a fortress situation end game when you can’t afford to wait cognitive brain to calculate new variations after each single move.

And also, Caruana would have had to trap his knight in a corner to get the win. To quote Kasparov:

The computer shows Black wins with 68..Bh4 here. But had Caruana played the incredible 69.Bd5 Ne2 70.Bf3 Ng1!! they would request metal detectors immediately! No human can willingly trap his own knight like that.

Personally, I’m not convinced that the win was beyond the ability of any human to find. Previous generations of players spent much more time studying the endgame (as opposed to endless openening preparation), and I can see Fischer or Capa, or maybe Botvinnik, finding it over the board.
