First, a failure worth studying. I told my AI agent to build one useful app every day. It produced unit converters, color pickers, base64 encoders. Statistically average, completely forgettable. Nobody cared. Then I changed one word: “experiments” instead of “apps,” with specific creative direction. One of those experiments hit #3 on Hacker News. The lesson: AI execution costs dropped to near zero. The only competitive advantage left is human taste and vision.

Then, applying that lesson to revenue. I directed my agent to package what I know into digital products and sell them. $355 in three weeks against $400/month in AI costs. Near break-even on month one. The real story is the “execution gap”: most experts never monetize their knowledge because packaging, marketing, and distribution are hard. The agent handles all of that. What happens when that gap closes for everyone?

Finally, where this is heading. I ran Qwen 3.5, a 9 billion parameter model, on my MacBook and iPhone. No cloud. No subscription. No internet. The gap between local and cloud AI is closing fast. If you can run capable AI on hardware you already own, the barrier to entry for everything above collapses.

The thread: AI needs human direction to create value. The tools to provide that direction are becoming radically cheaper. The bottleneck isn’t technology anymore. It’s having something worth saying.

First, a counterintuitive discovery: more instructions made my agent worse. I went from 471 lines of rules down to 61 by replacing abstract adjectives with concrete behaviors. “Principle beats rule” turned out to be the single biggest performance unlock.

Then, teaching it to learn. Error logging, structured lessons, and an identity layer that knows who I am. But MIT research shows personalized profiles increase sycophancy by 33-45%. The AI starts telling you what you want to hear instead of catching your mistakes. True autonomy requires friction, not agreement.

Finally, giving it a physical home. Migrating to a dedicated Mac Mini broke everything: no display meant no UI automation (solved with a virtual 5K screen hack), hundreds of hard-coded paths pointed to folders that didn’t exist, and the agent burned through API credits stuck in silent error loops. The fix: full root authority inside a contained blast radius. If the AI deletes the entire drive, it literally doesn’t matter.

The payoff: a self-improving agent running 24/7 on its own machine, with its own iCloud account, reachable via iMessage like a coworker.

I’ve been writing Digital Thoughts for a while now, and some of you told me you’d rather listen than read. Fair enough.

So I’m experimenting with a podcast version - AI-generated conversations based on my posts. Not me reading articles out loud, but two AI hosts digging into the ideas, arguing about them, and finding connections I didn’t even see when writing.

This first episode covers the full arc of building Wiz - my personal AI agent. From “why would you build your own instead of using ChatGPT?” to the moment it started writing its own skills without asking. We get into the failures: tasks that looped infinitely, passwords changed twice in one night, and the counterintuitive discovery that downgrading to a cheaper model made the whole thing better.

If you’re hearing this on Spotify or Apple Podcasts - every episode is based on posts from Digital Thoughts , where I write about using AI daily as a practitioner, not a pundit. Subscribe there if you want the full picture.
