I'm not sure many/any serious scientists take it seriously. It's interesting, but it's far from peer reviewed journal type material.
There's nothing you can say to make this person consider your viewpoint.
But like a lot of intelligent ideas now days...if it doesn't fit someone's narrative it's immediately discredited and discarded.
Only the experts who agree with the narrative are to be taken seriously.
It's become a real problem to discredit ideas that disagree with ones narrative even if they're from expert sources.
