A true amateur will never win the Main Event
Someone like Moneymaker/Raymer/Gold/Yang will never win the Main Event. The caliber of play is too strong, and too many smart tough players are using GTO strategy.
We saw in the heads-up how Griff, despite having the chip lead, was badly outplayed. Heads-up NLHE has been solved by computers, and Tamayo has GTO down to a science.
One can argue that it's bad for poker, as poker needs a charismatic likable amateur (and/or a woman!) to win the Main Event in order to experience another poker boom.
