Why Opus 4.5 Just Became the Most Influential AI Model

The world changed last week—Opus 4.5 is the best coding model Dan has ever used. It can keep coding and coding autonomously without tripping over itself—and it marks a completely new horizon for the craft of programming. The dream is here: You can write English, and make software. We had Paul Ford on AI & I to talk about it. Ford is the co-founder of Aboard and also a prolific writer. He authored one of Dan’s favorite pieces of technology writing What Is Code?—so he’s the perfect person to unpack this with him. We talk about the wonder—and genuine unease—that comes with using tools this powerful. We also get into what people who love technology should care about as the ground under us shifts faster than we can imagine.
