The interface is no longer a tool. It is a collaboration.

Traditional interfaces wait. AI interfaces propose, infer, and sometimes act. That shift changes the relationship between product and person.

Designers now shape a collaboration: how the system asks, explains, remembers, and recovers.

From flows to negotiation

A rigid happy path is not enough when the product can produce many valid outcomes. We need boundaries, checkpoints, and ways to steer without starting again.

Good collaboration feels fast without feeling out of control.
