Peter Cullen has died

What's this about?

Peter Cullen, the voice of Optimus Prime since 1984 and of Eeyore, has died.

Why is this in an AI digest?

Because voice is the specific creative profession the day's other big thread was about. The Gemini Omni comments turned into an argument about voice actors and unionisation, and Cullen is the strongest possible case for what is at stake: a single performance so identified with a character that four decades of recasting attempts failed, and one that a model can now approximate from a few minutes of audio.

Why is it worth noticing?

1. His Optimus Prime performance was reportedly modelled on his brother, a Marine, who told him a real hero is quiet and doesn't need to prove it.
2. He voiced the character across four decades and multiple continuities — an unusual continuity in an industry that recasts constantly.
3. Read alongside the Gemini Omni thread, which spent 143 comments on exactly this question.
