My second book on AI, Co-Existence, is out today (and you can get it here), 30 months after the release of Co-Intelligence in early 2024. Looking back across the gap between these books is a good way to get a sense of AI progress. And, thanks to AI, I can describe this progress with some quite lovely charts.

Making the charts is itself a good indicator of how far things have come. In the era of chatbots, the era of Co-Intelligence, I would have had to work back-and-forth with an AI in a chat window, guiding it through each new step. In the current era of agentic AI that I cover in Co-Existence, I delegated the work and let the AI handle it. In this case, I used Opus 5.5 in Claude Projects, which allows you to talk to a single “orchestrator” agent that then spins off additional agents as needed, giving them instructions and relaying information back to you. Getting the work done was straightforward. I gave the AI a couple sentences of suggestions and it did what would have taken me hours of work (all the research, all the graphing, all the layouts, all the images, all the citations…) in minutes. And since I didn’t have to do the work, I had the AI make many options for me. I picked some and gave handwavy reactions to others that would drive a human team mad (“make it better”). It even caught that I’d gotten the math wrong. I was going to call this post “28 months on the exponential.”
