The shift from mockups to code is one thing. The shift from designing tools to designing autonomous behavior is another. Sergio Ortega proposes expanding Human-Computer Interaction into Human-Machine Interaction. The label is less interesting than what it points at.

The part that matters for working designers is the transparency problem:

This is where design must decide what to show, what to simplify, and what to explain. Absolute transparency is unfeasible, total opacity should be unacceptable. In short, designing for autonomous systems means finding a balance between technological complexity and human trust.

When a system makes decisions the user didn’t ask for, someone has to decide what gets surfaced. Ortega:

The focus does not abandon user experience, but expands toward system behavior and its influence on human and organizational decisions. Design is no longer only about defining how technology is used, but about establishing the limits of its behavior.

And the implication for design teams:

When the machine acts, design becomes a mechanism of continuous balance.
