According to Tyler Cowen, that's how this postgame interview from Gibraltar 2018 is often characterized. That seems implausible, if one takes "all time" seriously. And there's not so much of an interview, either: Vassily Ivanchuk is asked about the game he just played, and off he goes. Regardless of the superlatives, it is a terrific whatever-we-want-to-call-it. Ivanchuk does a brilliant job of recounting the game and his analysis without looking at a board, and does it with such boyish enthusiasm and love for the game that it's infectious.
If you, like me, missed this back in 2018, please do yourself a favor and watch it now.
