Copyright law in the US only applies to human-made creations, but AI characters like Tung Tung Tung Sahur are challenging that

One of the most beloved characters in an absurdist genre of online video content has become the center of an international legal battle that could determine where human creativity ends and artificial intelligence begins.

Tung Tung Tung Sahur, also known as Triple T, was created in 2025 by an Indonesian teen who goes by the username Noxa, using OpenAI’s image-generation tool. Based on a kentongan – a type of drum used to wake south-east Asian Muslims for their pre-dawn meal during Ramadan – the character is an anthropomorphized version of the instrument with a broad smile and a vacant stare. He sits under the umbrella of “Italian brain rot” internet videos.

On the other is Airbnb, the San Francisco-based booking colossus. The battle between them is over the three little letters they share.

Writers are voicing their anger at AI theft of their work with ‘Human Authored’ logos and an empty book. The government must listen

In a scene that might have come from a dystopian novel, books were being stamped with “Human Authored” logos at this week’s London Book Fair. The Society of Authors described its labelling scheme as “an important sticking plaster to protect and promote human creativity in lieu of AI labelled content in the marketplace”.

Visitors to the fair were also being given copies of Don’t Steal This Book, an anthology of about 10,000 writers including Nobel laureate Kazuo Ishiguro, Malorie Blackman, Jeanette Winterson and Richard Osman, in which the pages are completely blank. The back cover states: “The UK government must not legalise book theft to benefit AI companies.” The message is clear: writers have had enough.

After years of court action and complaints, trademark office in Spain rules name is counter to ‘public order and morality’

A Spanish restaurant chain called The Mafia Sits at the Table may soon have to change its name after the country’s patent and trademark office heeded objections from the Italian government and ruled that the brand’s nomenclature ran counter to “both public order and morality”.

Italy has pursued its claim against the chain – known in Spanish as La Mafia se sienta a la mesa – through various courts and official bodies over the past few years, alleging that the name trivialises both organised crime and efforts to fight it.

The human impulse to steal has been accelerated by AI, inequality and our political leaders – with profound consequences

Last week I discovered that an article I wrote about the England cricket team has already been copied and repackaged, verbatim and without permission, by an Indian website. What is the appropriate response here? Decry and sue? Shrug and move on? I ponder the question as I stroll through my local supermarket, where the mackerel fillets are wreathed in metal security chains and the dishwasher tabs have to be requested from the storeroom like an illicit little treat.

On the way home, I screenshot and crop a news article and share it to one of my WhatsApp groups. In another group, a family member has posted an AI-generated video (“forwarded many times”) of Donald Trump getting his head shaved by Xi Jinping while Joe Biden laughs in the background. I watch the mindless slop on my phone as I walk along the main road, instinctively gripping my phone a little tighter as I do so.
