Ethan Mollick reviews Google's new Gemini 3 AI model and reflects on how far the technology has come in the last three years. Contrary to the many people who have proclaimed that AI has stopped improving or reached a cognitive plateau, it appears that it's still getting better. "Three years ago, we were impressed that a machine could write a poem about otters. Less than 1,000 days later, I am debating statistical methodology with an agent that built its own research environment. The era of the chatbot is turning into the era of the digital coworker." I'm still writing articles and OLDaily posts without AI assistance, and that won't change, but it's getting hard for me to imagine doing anything technical without AI assistance.
