Hi, neavvy
Really if it can be easy to deceive the human eye, using the Deepfake very well can confuse those who are not very attentive to the physical features of a person when issuing a statement or giving orders, although there are people who they watch or watch the video and pay attention to what they are saying there are also people who only listen and do not watch the video or pay attention to these things.
With regard to public opinion, if those who provide the news confirm the source very well there can be no problems, because everything will be in a false news or to create controversy, so it is good to verify the information before sharing it in the media.
I used Google translator
I am really grateful for your reply dear @suanky
Yes, this is definitely a great practice. And we, as individualities, need to check every source of information in order to prevent social misinformation.
