Are AI chatbots making us lose control of our brains?

Gloria Mark’s device-use studies found average adult attention spans fell from about 2.5 minutes in 2003 to 47 seconds across 2014–2020, and she warned that ChatGPT, Claude, and Gemini shift summarizing and evaluation work away from users’ own cognitive processing.

Why it matters: HKR-H/K/R all pass: MIT Technology Review frames a sharp chatbot-cognition concern and cites Gloria Mark’s attention data. It is still commentary, not a product, paper, or policy move, so 73 fits the featured floor.
