For some memes and funny videos, I accept an AI creation, but if I want to listen to a lecture, a podcast or follow a blogger, I want it to be that person.
Because if it's not a person personally (eg, Achim Beda 🙂), I don't want to look at AI, because then it can be anyone with knowledge of working in AI tools.

In the end, with the third version I would feel cheated, and as your avatar, I would prefer to accept the second (animated) version, with which you successfully hide your identity, but make it clear that you are an AI.
