After coming across this theory, which seems rather compelling, I realize that I need to go back and look at some old footage of cities which has been restored and colorized with cutting edge AI. We could even restore footage that no one else has looked at yet.
There are probably abnormalities that can be spotted, especially in cities where buildings just happened to be destroyed due to some freak accident.
This example comes to mind:
Upscaled with neural networks trip down Market Street, San Francisco, shot on April 14, 1906, just four days before the San Francisco earthquake and fire which killed an estimated 3 000 people and destroyed over 80% of the city of San Francisco.
You're on drugs.
