AI×HI is shorthand for the relationship between artificial intelligence and human intelligence: the multiplication sign is the point. Not AI replacing humans, not humans using AI as a tool, but two different kinds of intelligence whose combined output depends on how the relationship between them is designed.
The premise behind the term is that the relationship already exists. If you work with AI daily, you have one, whether you chose its terms or not. Most people run it on defaults: habits carried over from human coworkers, trust calibrated by mood, no agreed division of labor. The essays in this series examine what happens on those defaults (dependence, compression, misplaced expectations about memory and voice) and what changes when the relationship is designed deliberately.
AI×HI deliberately avoids both poles of the usual debate. "AI as tool" understates how much the interaction changes the human in it. "AI as threat" overstates the machine's independence from the human who shapes it. What remains is a working relationship between unequal but mutually dependent parties, and like any working relationship, it can be left to drift or it can be managed with intention.
