That stood out to me, too; I wonder if that model assumes the shrinkage of the Pacific reverses when the Atlantic starts to close. strange. I also didn't see them try to account for the rifting in Africa, perhaps they assume that will fail to complete like the North American one did

This scenario is one possible projection; it assumes the eventual development of a subduction zone in the West Atlantic that would overcome the spreading at the mid Atlantic ridge, eventually sealing the basin. I don't understand the mechanisms well enough to know how that prediction was made, so someone with more experience on the subject can chime in.

Agreed, Chris is such a great musician.

Here's to hoping they learned their lesson from SotS, but I'm not holding my breath.
