This is horrifying in terms of scamming, ransom threats and phishing.
Eg calling as the CEO in the CEO's voice urgently asking for a password, wire or data.
People calling your family saying its you based on some youtube video, asking for immediate financial help.
People saying someone has been kidnapped and they need a ransom. This is uncommon in the US but happens all the time to elderly in places like Mexico. With this tech scammer cartels can control your voice from a prompt to muppet distressed requests to the people you care about. In my opinion, these type of services should be banned by some kind of regulation.
Useless gesture considering that this type of technology using repositories such as tortoise and taco Tron Will be wildly available running from one's own personal computer within a few short years. Might as well air the dirty laundry in public so we can determine how to deal with the threat instead of pretending it doesn't exist by banning it, and have it appear in stealth a few short years later.
