I'm afraid AI generated but real looking salsa dance videos will be posted soon and you can't say anymore if it's real or not. Or a real known dancer can be simulated by faking a dance from him/her. I don't see what's the incentive to do such things but some people enjoy to fool others. Or there is a financial incentive.
Back in 2021 after the perseverance rover landed on mars there were NASA videos on YT showing collections of photos in superb quality, I enjoyed watching (those were covid days at home). A bit later several accounts appeared with fake photos showing martian skeletons or martian house ruins in the sand, without saying it's fake but suggesting it's real. Simple minds may believe that. One of the accounts had an italian name: Italy has high unemployment amongst youngsters so I wondered if some guy from there tried to earn money this way because he couldn't find a real job. Google tells me for 1 million clicks on YT you may earn 1000 dollars, so that would be an incentive. Salsa videos don't get so much clicks so others will be faked much earlier. But if any photo or video can be faked what will we believe still? Maybe some people will lose interest in internet and start enjoying real people again. Or it doesn't matter anymore as long as that video is entertaining.
