And this isn't something new. Magnus has been doing this for a few years now, after getting bored of facing the same over prepped opponents. He has mastered this technique, and showed that he's still the GOAT at mid to late game positions once the opponent is out of prep. But again, he's not doing this "randomly", he's studying when and where he can do it to temporarily get a disadvantage that will sort itself out later in the game. And engines are heavily used still.

It’s a self reinforcing system. We need a major disruption to move on from it.
