All the rape, torture, and murder will be brushed under the carpet, a great lesson for any future war criminals.

The Maybe

Great @themaybe.org podcast with the inimitable @alixdunn.com diving into AI, video, trust and human rights. Loved deep diving into how what we've learned at @witnessorg.bsky.social over decades of video activism drives our work to defend visual truth in age of Sora www.themaybe.org/podcast/stra...

#mustread Every day I wish there was a way to keep all the AI generated content out of my IG feed. So tired of seeing 'people' who don't actually exist.

โ€œthe deeper damage is a fog of doubt settling over everything we seeโ€

@samgregory.bsky.social urges us to consider that soon our shared basis of reality will no longer be trustworthy and risks being undermined by generative video... and offers how to fight that.

@samgregory.bsky.social has written a fantastic piece on the risks of deep fakes and what can be done about them. As he correctly points out: "When any piece of evidence can be credibly dismissed as synthetic and any fabrication defended as real, we lose the ability to establish shared truth."

Last week I wrote about the racist narratives being pushed about SNAP benefits, including unhinged AI videos on TikTok

Fox News however ran a story claiming those videos were real until they realised their mistake and changed the story without admitting their mistake.

Starmer v Starmer: why is the former human rights lawyer so cautious about defending human rights? The long read: Given his career as a human rights barrister, it was hoped Keir Starmer would be the PM to restore the UKโ€™s commitment to international law. The reality tells a different story

Good morning, I've written a piece about the prime minister. I spoke to several dozen sources, including government insiders, former legal colleagues and campaigners to ask: what happened to Keir Starmer the heroic human rights lawyer? www.theguardian.com/politics/202...

I made an AI clone of my dead son - and let a journalist interview him An interview between a US journalist and an AI clone of a teenager who was killed during shooting at his school has prompted criticism online.

Griefbots are increasingly common in personal usage while static resurrection deepfakes are used for advocacy and entertainment, but what does it mean to interact with an avatar of a dead person for political advocacy? I talked to BBC about THAT interview by Jim Acosta.
