I was chatting with a friend over coffee the other afternoon about nothing in particular, and inevitably the topic turned to AI. After all, I coordinate a United Nations-backed group of AI experts, and he makes his living creating AI-generated videos. “Can’t live without it,” he said casually, like he was talking about electricity or running water.

Because of the work that I do, I asked what felt like an obvious question, “Do you ever wonder what AI might be costing the planet?” He paused, looked away, and thought for a moment. “No idea,” he confessed.

I nodded, because the truth is, most days, neither do I.

Talk big, forget the bill

We talk about AI in big words. Transformative. Disruptive. World-changing. I am guilty of describing AI in these superlatives, as if it were a force of nature rather than a set of systems engineered by people.

But for all the AI awe, one word rarely finds its way into coffee table conversations: sustainability. Colleagues debate the future of work. Friends compare the best AI features on their smartphones. But too often, sustainability appears as a footnote, if at all.

This absence matters. Talking about AI without sustainability is like learning to cook without ever talking about turning off the stove. Things might seem fine for a while, but the electricity bill grows and the system overheats. Then, something starts to burn. AI is no different.
