They totally fucked this up. AI dubs "aren't there yet." They're still years away from being decent enough to get the job done.

If they really want to save money using AI, the correct way, with today's technology, is to use an AI voice changer! Hire a real voice actor and then make them do all the voices, then use the AI voice changer to make them sound like each character.

...but they're so fucking cheap and lazy they won't even do that.
