Individual impersonators are not the threat. It's the glut of impersonators that will present the real challenge. It would be very helpful to see a study done with these platforms as they mature to determine what percentage of the population is more easily fooled by these.

For example, as an individual with hearing problems, I may not be so easily able to determine a synthesized recording from an actual recording - for a short period of time. With longer recordings it may become more obvious.

Yes, but imagine a human impersonator who has infinite time to take requests from anyone and generate free recordings of any person with a substantial online audiovisual presence.

Bad joke of the day: Even Trump can't do it, and he really is President of the U.S.!
