Rhiannon Williams examines AI avatars in MIT Technology Review
Markdown · JSON · Original source
MIT Technology Review published this newsletter on September 4, 2025. Rhiannon Williams describes visiting Synthesia and supplying what the company needed to create a hyperrealistic AI-generated avatar of her. She found it “as unnerving as it is technically impressive”: it looked enough like a high-definition recording of a corporate speech that someone who did not know her might mistake it for one. Williams argues that her avatar illustrates how difficult it is becoming to distinguish the artificial from the real. She also predicts that avatars will soon be able to talk back, and asks what interacting with AI clones might do to people. Her account conveys the unsettling effect of a convincing likeness, but it is based on her experience with one company’s avatar, not evidence about how people generally respond. The newsletter points readers to the full story for more; this retrieved text does not include that story’s fuller account of the avatar or its possible effects.

Open question
What might interacting with AI clones do to people, beyond the unsettling effect Williams describes from seeing her own avatar?
Source-stated
Rhiannon Williams says she visited Synthesia and supplied what the company needed to create an AI-generated avatar of her.
Earlier this summer, I visited the AI company Synthesia to give it what it needed to create a hyperrealistic AI-generated avatar of me.
Source-stated
Williams describes her avatar as technically impressive and unnerving, saying it could pass for a high-definition recording to someone who did not know her.
It’s slick enough to pass as a high-definition recording of a chirpy corporate speech, and if you didn’t know me, you’d probably think that’s exactly what it was.
Source-stated
Williams argues that distinguishing the artificial from the real is becoming harder and predicts that avatars will soon be able to talk back.
My avatar shows how it’s becoming ever-harder to distinguish the artificial from the real. And before long, these avatars will even be able to talk back to us.
Escape Meridian interpretation
Escape Meridian reads Williams’s account as a warning about the unsettling human effect of a convincing likeness, while the retrieved newsletter leaves broader effects on people unanswered.
I found my avatar as unnerving as it is technically impressive.

attribution — pass: The avatar segment of this newsletter issue is credited to Rhiannon Williams and published by MIT Technology Review, matching the reading. The Download comments on items in its own words, so it is one piece, not a bare listing.
Synthesia’s AI clones are more expressive than ever. Soon they’ll be able to talk back. —Rhiannon Williams
summary — pass: The reading faithfully covers the Synthesia avatar segment, keeps Williams's voice ('unnerving as it is technically impressive') and her open questions, and is readable without specialist background. It focuses on one segment of a multi-item newsletter, which is reasonable. It omits that the avatar came from Synthesia's latest model, introduced the month before, but this does not distort the meaning.
I found my avatar as unnerving as it is technically impressive.
date — pass: The reading states September 4, 2025, which matches the UTC day of originalPublished, 2025-09-04T12:10:00Z. It discloses the archived copy. 'Earlier this summer' is not made more precise. The talk-back claim is presented as Williams's prediction, not an outcome. The reading uses none of the later sidebar or related-story material.
And before long, these avatars will even be able to talk back to us.
support — pass: Each claim matches the source text. The interpretation is labeled as Escape Meridian's, cites a source excerpt, and stays modest. The question comes directly from Williams's own question. The limitations correctly note that this is one person's experience and that the retrieved text does not include the full story.
But how much better can they get? And what might interacting with AI clones do to us?
media — pass: No media was selected, and no verified media candidates were supplied, so nothing needs checking.
