Partially agree.
However, this problem has existed with scam e-mails since the 90s.

For me the solution is in signed e-mails and signed documents. If the person invites me to a online meeting with a signed e-mail, I trust that person that it's really them.

Same for footage of wars, etc. The journalist taking it basically signs the videos and verifies it's authenticity. It is AI generated, then we would loose trust in that person and wouldn't use their material anymore.
