While accordions can simplify long content pages and minimize scrolling, they diminish content visibility and increase interaction cost. On desktop, use accordions for content-heavy pages where users will not need to access content under several accordions.

Avoid using accordions when: 1. Users need access to most content; 2. There's little visible content on the page; 3. Content is complex with multiple levels; 4. Content can't be effectively chunked; 5. An uninterrupted reading flow is prioritized.

AI is introducing the third user-interface paradigm in computing history, shifting to a new interaction mechanism where users tell the computer what they want, not how to do it — thus reversing the locus of control.
