After Disney releases a new film in English, the company will go back and localize it in as many as 46 global languages to make the movie accesible to as wide an audience as possible. This is a massive undertaking, one for which Disney has an entire division -- Disney Character Voices International Inc -- to handle the task. And it's not like you're getting Chris Pratt back in the recording booth to dub his GotG III lines in Icelandic and Swahili -- each version sounds a little different given the local voice actors. But with a new "AI dubbing" system from ElevenLabs, we could soon get a close recreation of Pratt's voice, regardless of the language spoken on-screen. ElevenLabs is an AI startup that offers a voice cloning service, allowing subscribers to generate nearly identical vocalizations with AI based on a few minutes worth of audio sample uploads.

We consider a sequence of repeated interactions between an agent and an environment. Uncertainty about the environment is captured by a probability distribution over a space of hypotheses, which includes all computable functions. Given a utility function, we can evaluate the expected utility of any computational policy for interaction with the environment. After making some plausible assumptions (and maybe one not-so-plausible assumption), we show that if the utility function is unbounded, then the expected utility of any policy is undefined.
