Gloria Mark borrowed the vocabulary of physics to describe an empirical asymmetry in cognitive work. Kinetic attention is the active engagement visible in output: the worker focused on a task, producing results, measurable on any dashboard. Potential attention is the reserve capacity — recovering from the last engagement, consolidating recent learning, preparing to engage the next task with full resources. The healthy workday requires both, in alternating cycles. The culture of knowledge work, however, systematically overvalues the kinetic and undervalues the potential, because kinetic attention feels productive while potential attention feels like slacking. The AI-augmented workflow accelerates this bias toward pathological extremes.
The distinction matters because the two forms of attention are not interchangeable. A worker who operates continuously in kinetic mode — who converts every moment of potential attention into productive output — depletes the reserve that kinetic attention draws upon. The depletion is not immediately visible. Output continues. The worker feels productive. But the quality of the engagement degrades, the judgment narrows, and the cognitive system that produces the output approaches a state that Mark, without dramatizing it, simply describes as running on empty.
Mark's research has identified the conditions under which healthy alternation occurs. It is rarely the product of individual planning. It emerges from the natural structure of work itself — the waits, the transitions, the moments when the activity pauses and the worker has nothing to do but stand still. These moments were not experienced as valuable in the pre-AI era; workers, if asked, would have said they wanted less of them. The default mode network, however, did not ask the workers' permission. It activated automatically in the gaps the workflow provided.
The AI-augmented workflow collapses the gaps. The tool is always available. The next prompt is always possible. The culture rewards continuous engagement. The internal imperative to achieve — what Byung-Chul Han calls auto-exploitation — converts every moment of potential attention into kinetic attention, because the environment makes the conversion feel not just available but obligatory.
The consequence, in Mark's framework, is a cognitive monoculture. The worker operates in kinetic mode continuously, converts all available potential into kinetic, and arrives at the moments requiring the most cognitive capacity — the architectural decision, the creative breakthrough, the judgment that matters — with the potential reserve already depleted. The judgment barrier that Segal identifies as the remaining human work is precisely the work most vulnerable to potential-attention depletion.
Mark has used the kinetic/potential distinction in her lectures and writing for over a decade, drawing loosely on the physics metaphor but grounding the concept in her empirical observations. The framework became central to her work on AI because it names precisely what the AI workflow eliminates: not time, not effort, but the reserve capacity that sustains sustained performance.
Attention has two modes. Kinetic attention is actively engaged; potential attention is reserve capacity held for recovery and preparation.
The healthy workday alternates. Sustainable cognitive performance requires cycles of engagement and recovery, not continuous maximum engagement.
The culture biases toward kinetic. Visible productivity is rewarded; invisible recovery is dismissed as slacking or optional.
AI accelerates the bias. By making productive engagement available in every interval, AI converts potential attention into kinetic attention continuously, depleting the reserve.
The depletion is invisible until it matters. The worker notices nothing until a moment requiring peak judgment arrives — and the reserve that would have supported the judgment is gone.
