You can follow along CMU’s deep RL course, they post which research papers they go over here: https://cmudeeprl.github.io/703website_f22/lectures/

You raise some really good points. I really don’t know too much about this area, but one idea is to use some sort of blockchain technology at point of capture to verify the integrity of images/videos.

You are right in that we can already create fake news. I also do think that for the most part generative models are going to lead to some really interesting content being created. That being said, I believe that it will make creating fake news significantly more accessible then it currently is which is why we should exercise caution with the development of these tools

What sort of solution could help in this case?

This may be true, but the CGI you see in Hollywood can run for hundreds of thousands of dollars. The threat with generative models is just how accessible it will be for anyone to make fake news if they choose to, regardless of their budget.
