    16 Agent Patterns: An Agent Engineering Primer Agent engineering illustration

    Any sufficiently advanced technology is indistinguishable from magic. — Arthur C. Clarke

    What are AI agents? Simon Willison crowdsourced a lot of definitions that focus on:

    1) Using AI to take action on the user’s behalf in the real world (i.e. what the agent does)
    2) Using AI to control a loop or complex flow (i.e. how the agent does it).

    An AI agent takes a sequence of actions based on an AI-determined control flow.

    Agents use prompts as the CPU of a Turing machine that can manage state, memory, I/O, and control flow. The agent can access the Internet and tools to perform compute tasks, retrieve info, take actions via APIs, and use the outputs to determine next steps in a loop or complex control flow. Maybe even control a browser or computer.

    In this post, we’ll try to develop a roadmap of agent concepts and patterns to learn, and resources to learn them.

    The AI Economic Singularity is Near
    Robot barista declines job application from human

    Economics is the painful elaboration of the obvious.

    Politicians sometimes say things like “AI is going to make our workers more productive, and they will reap the rewards with higher wages.”

    It’s mostly worked out the way in the past. But the labor share of income has varied. How much labor benefits, and how much capital benefits, depends on how technology complements labor, versus substitutes for it. There is little support in economic theory for the notion that technological progress always raises everyone’s wages and standard of living. It’s a pop economics, Panglossian belief based on motivated thinking.

    AI is the most human-like technology ever invented, so it seems likely to be an effective substitute for human labor. It seems likely that we will get growth but also disruption, more income inequality, more concentration of wealth, and more people locked out of decent middle class and working class jobs. The worst case would be an ‘economic singularity’ of robots making more robots while masses are immiserated. We should think about how to detect the singularity and use policy to head it off.

    Let’s break it down (painful as it may be).

    Practical ChatGPT Prompting: 15 Patterns to Improve Your Prompts

    A logician is hiking through snowy woods and sees a small spaceship, and next to it, two tiny legs, sticking out of a snow drift. He digs the little creature out, and it turns out to be small omniscient space alien. The alien is extremely grateful and, being omniscient, offers to answer any question the logician may have. Naturally the logician asks: “What is the best question to ask and what is the correct answer to that question?” The tiny alien pauses momentarily, and replies, “The best question is the one you just asked; and the correct answer is this one.” And just like that…the alien hops in their spaceship and flies away.
