I've ran hunyuanvideoai from their GitHub and it seems to generate realistic videos. It is a bit slow (30-60min per video clip) and requires ~50GB VRAM. I wonder how the quality compares though?
Firearm related X is the wrong thing to measure. Obviously if guns are truly banned, there will be no gun crime. There will still however be knife crime, fist crime, car crime, etc.
The thing we want to measure is if we can (as a country) live our lives in peace. Better measures of this might be all crime, violent crime, life-span related measures, or even mental health and drug abuse.
Banning one specific thing does not change human nature. We need to take a holistic view to address many issues underlying violent crime, firearm related or not.
