Regulation is fine, but prohibition rarely works.
Here's the thing, you're almost most likely to be successful as a scammer with a poor deepfake with a good deepfake.
This is why so many scams are so unbelievable in their premise (Nigerian princes , UN Lottery, etc...). Falling for the premise is a good indicator that the leads they get will turn a profit because they indicate vulnerability.
This is partly why I don't think regulation would stop much of the scamming.
So I think it does matter how authentic the deepfake appears. I’m ambivalent on whether banning the technology is a good idea or even how feasible it could be, but to the extent that deepfakes are limited I do think it would be bad for scammers.
But there's a thousand other ways to get that exact info, even/especially online.
But you can Google "the anarchist cookbook" and get that information just fine (for better or for worse[1])
