Beware what you tell your AI chatbot. It’s not a shrink – it’s a snitch | Arwa Mahdawi

In a case of ‘oh dear diary’, the OpenAI president Greg Brockman is having to read extracts from his musings about Elon Musk in court. It’s a terrifying reminder that what’s divulged to AI really isn’t private

The hottest new read of 2026 may well be The Secret Diary of Greg Brockman, Aged 38¾. It’s got everything: feuding billionaires, scheming CEOs and a perhaps somewhat unreliable narrator. You won’t find it in the library, but you can watch Brockman, a co-founder and president of OpenAI, being forced to read the juiciest bits out loud in court.

Before you ask ChatGPT to explain, here’s the backstory: Elon Musk is in a legal battle with Brockman and the OpenAI CEO, Sam Altman. Musk, a former board member of OpenAI, is accusing the men of violating the AI firm’s founding agreement by turning it into a for-profit entity. Meanwhile, Altman et al are arguing Musk is just upset he’s not in control of the company and wants to bring down his competition.
