He's been writing specifically about AI models and AI developments since 2015, before most people even knew what AI stood for. Since AI has become a household term, his expertise has helped millions of people understand what's going on under the hood and how they can make the most of AI in their work and life. His writing has appeared in the The New York Times, Wired, Popular Science, and Inc. Based in Dublin, Ireland, he's also a photographer. His photos have been published on hundreds of sites—mostly without his permission.
