My first life was as a software engineer. I co-wrote ClarisWorks, with Scott Holdaway, and sold it to Claris. For a few years it was a $100 million product.In 1999 I went back to grad school to study artificial intelligence (though my thesis wound up being on games and computation!). My lifetime goal is to recreate human-level intelligence. I study both traditional artificial intelligence and computational neuroscience to pursue this goal (while keeping one foot in games & theory).If I ever return to the software industry, in a non-AI context, it will be to push the ideas behind ClarisWorks into the 21st century. It had a lot of unfulfilled potential.
