Building AI that upgrades humans.

Hi,

My name is Daniel Miessler and I'm an AI / Security Researcher and entrepreneur based out of the San Francisco Bay Area. My focus is on building AI systems that augment human capabilities rather than replace them.

My goal is to help prepare people for a world where AI removes the traditional, corporate labor model—and move us towards something better—which I call Human 3.0.

To look around, you can check out my writing, telos, projects, ideas, and/or predictions—or a deeper version of this explainer on the about page.
