Linda Stone
The technology industry insider who named continuous partial attention, documented screen apnea in over two hundred participants, and established that attention is not a resource to be allocated but a relationship to be tended—the most precise diagnostician of what AI-augmented scanning does to the human capacity for presence.
Linda Stone is the scientist of attentional quality. She worked at Apple in the late 1980s and at Microsoft through the 1990s, which gave her the particular epistemological advantage of watching intelligent, capable people adopt powerful technologies from inside the adoption—and noticing, before anyone else had the vocabulary for it, that what she was watching was not the augmentation of human cognitive capacity but its qualitative transformation. The state she named
continuous partial attention is not multitasking—sequential switching between tasks, each with its measurable switching cost. It is a different state: the mind cast wide across every channel simultaneously, maintaining ambient vigilance across all of them, processing at a level sufficient to detect anomalies but insufficient for the depth that genuine understanding requires. Her foundational reframing is that attention is not a resource to be allocated but a relationship to be tended; the quality of the attentional relationship—its duration,
