The Synthetic Reality Problem
When evidence becomes manufacturable at scale, trust in shared reality becomes a public utility under attack.
A society can survive a lie. It cannot survive the loss of the category lie.
For most of recorded history, a photograph, a recording, a video, a document carried evidentiary weight, not because any of them were perfect, but because forging them at scale was expensive. That cost is collapsing. The marginal price of a convincing synthetic image, a synthetic voice, a synthetic video of a named human being saying something they never said, is approaching zero.
The consequence is not, primarily, that people will be fooled by individual fakes. The consequence is the corrosion of the entire epistemic substrate: the slow erosion of any default trust in evidence at all. When everything can be fabricated, nothing has to be denied. The liar wins not by being believed but by making belief itself optional.
This is not a problem any single platform can solve, and it is not a problem any single watermarking standard can solve. It is a civic infrastructure problem. Shared reality is a utility. It has to be maintained, defended, and funded, like water, like roads, like elections.
This chapter records the moment that maintenance stopped keeping pace with the attack.
