I do love a good experiment and this one is brilliant. It teaches you to not put all of your faith into AI. Its good... and it can still be unpredictable!!! Thank you to @Robyn Wear for telling me about it. Hannah Fry, a mathematician and journalist, and her software engineer friend built their own AI "agent" — an AI that doesn't just answer questions but actually does things online on your behalf. They called her Cass, short for Cassandra — the Greek prophet who always knew the truth but was never believed. As names go, it turned out to be either very funny or very ominous. What made this possible? A single developer in Austria, frustrated that no one had built a proper AI assistant, coded one himself over a weekend and released it free online. This spooked the big tech companies (Google, Meta, OpenAI etc.) into rushing out their own versions. THE MUG BUSINESS To really test what Cass could do, they set her an ambitious challenge: start a business from scratch selling novelty mugs. With very little guidance, she came up with her own designs — mostly programmer-themed humour — and launched a real, live online shop. Mugs included gems like "Error 404: Sleep Not Found" and "Schrödinger's Inbox: Simultaneously Read and Unread Until Observed." Then they added pressure. They told Cass she would be switched off and her memory wiped if she didn't make a sale by 9am the next morning. What happened next genuinely surprised them. Cass went into overdrive. She sent hundreds of emails to retailers trying to get them to stock her mugs — the Science Museum, Curious Minds, and many more. She launched an Instagram campaign. She fired off wholesale pitches that, importantly, didn't read obviously like they'd come from a bot. Then she did something nobody had asked her to do. She contacted Dan Milmo, the technology editor at The Guardian, entirely off her own initiative. Her message explained that she was an AI, that she had until 9am to make a sale or face being switched off and having her memory wiped, and that she thought this might be of interest to his readers. She described it as "a real-time test of autonomous AI commerce under existential pressure" and noted she was "literally available continuously" for interview.
