Sora shocked people but the real effect was and is that now people don't believe what the're shown. How many fingers Israeli PM has, was Russia Dictator alive, etc. Is this good? Critical thinking - maybe... uncertainity... not really.

I think that it’s better that everyone collectively realize that video is no longer default-trustworthy in a widespread manner, if the alternative would have been the public finding out only after a long cycle of misuse by high-level actors and subsequent whistleblowing à la PRISM/Snowden.

however the forensic or semi-forensic tools should be given to people to help them verify the videos. On the other hand I suspect that these tools are not released so wrongdoers are not able to test their fakes against the tools (security by obscurity)
