Auf wessen Seite steht deine KI?

Vision eines Second Brains in Nutzerhand

Keynote at World Usability Day 2026, held on November 12, 2026, at FHNW Brugg-Windisch (German language)

Whose side is your AI on? A vision of a second brain in the hands of its users.

AI assistants learn with us, know our context and act on our behalf. The machine acts, the human sets the limits. But whoever pays for the assistant decides its loyalty, and whoever owns its memory holds us in their hand.

The defaults of the next decade are being set now, before our second brain hardens into platform lock-in. Peter Beck sketches a second brain that belongs to us: how user interaction is changing, whom an assistant is loyal to and who owns its memory, and the principles with which designers can shape the way there in their own products.
