Does a photo of Bitcoin seed phrases communicate 512 bits? Scholars debate

In a debate with Toby Ord and Ryan Greenblatt, bubblingcreek argues a photo of four Bitcoin seed phrases on paper clearly communicates 512 bits under the common-sense meaning — more than 340. Ord had countered that choosing between two photos is one bit, and real-world photographs rarely exceed 340 bits; the disagreement hinges on freely chosen information versus information already staged in the scene.
