I believe we have been seeing this for longer than we think. 9/11 may have been simple computer modeling, but now we can simulate almost anything

Biden is one the first people that most people have noticed maybe being deepfaked. Having body doubles is one thing, because that doesn't take as much effort to see which is the actual person or not, though we still didn't think much of it before. Deepfakes were cool to watch evolve, but it has its terrible implications now. What if Meta (FB) can use their vast array of data from it's users to now possibly simulate events of a person and use it against them if needed? Something else I've been watching for a while now and thought may happen.

If they can successfully maintain and advance this tech, there will be no way to know the difference anymore, unless you maybe have the source file.
