Just about every Presidents’ Day I’ll hear car deals with voice actors pretending to be Clinton or Bush and also on TV people dressed up as Lincoln… so I dunno.
Impersonating someone like Lincoln in a car commercial is one thing, but it’s another is someone presented an impersonation as their actual voice in a documentary.
It’s also complicated by the fact that the AI voice is trained on his likeness and dubious as if the reproduction is a new creation or something else. Similar to the debate about GitHub Copilot.
