THE USABILITY SCALING LAW: DEATH OF USER TESTING?

By 2035, AI trained on massive usability data could revolutionize interface design, making predictive usability more effective than traditional user testing for common cases. Today's usability insights are scattered, but if unified and used to train AI, they could scale like other AI systems. Though it may take 100,000 hours of annotated research and cost hundreds of millions, the boost in UX productivity could save billions each year.

THERE SHOULD BE NO AI BUTTON

The AI button, often shown with vague icons like a magic wand, adds confusion and disrupts workflows by separating AI from regular tasks. As users grow more familiar with AI, this design will become outdated and fragment work. A better solution is contextual integration—like embedded AI teammates—that fit smoothly into workflows and allow natural, real-time interaction without switching modes.

THE GREATNESS TEST: WHAT IS YOUR BEST DESIGN WORK?

Designers should rethink what “greatest work” means, as true impact often lies beyond flashy projects. Most people need designs that are affordable, convenient, and reliable—more than just beautiful. Great design grows in cultures with shared values and long-term commitment, which are rare. Real greatness is about using your skills to tackle meaningful problems.

DUOLINGO'S SMALL UI SWITCH THAT CHANGES EVERYTHING

Duolingo replaced its punitive hearts with an energy system, using 25 units per lesson and rewarding bonus energy for correct answers. This change reframes mistakes as investment, adds variable rewards, keeps scarcity for monetization, and encourages more mistakes, which is key for better language learning.

USING SIMULATION MODELS IN UX RESEARCH

UX research is facing strain, not from collapse, but from weak, borrowed methods that lack depth as AI demands more predictive, scalable insights. Adopting tools like simulation modeling from social sciences can help researchers study complex behavior and guide decisions when traditional access to users is limited.
