Correcting the Evolutionary Mismatch in Human-Computer Interaction

The architects of the Information Age, the conglomerates of the attention economy, have failed all of us. They never put forth a technology to relieve us from the distress of an overwhelming cognitive load.

In the 20th century we were promised breakthroughs in speed, access, and measurement. In delivering them, we only increased the mediation required on the human's behalf. We were promised faster transportation and got faster bandwidth. We were promised better health and got better tracking. We were promised deeper connection and got Zoom calls and better feeds.

The crux of the issue is that all of these were just that: additions. They promised a relief we never received. In our society it has manifested as a reduction of our brains, the degeneration of the prefrontal cortex from being generative to handling trivial administrative processing. The very brains responsible for the steam engine, life-saving vaccines, and the moon landing, reduced to mere filing cabinets.

An evolutionary mismatch

This is a profound evolutionary mismatch (Riggs, 1993): a state where our ancient biological hardware (built for multi-sensory, social environments) is forced to operate in a modern, low-bandwidth digital environment it was never designed to navigate. We were promised relief and instead received more to manage, more to track, more to process.

The argument hinges on a biological reality: attention is a finite metabolic resource. True innovation must transition from additive to subtractive, minimizing extraneous stimuli to protect the brain's limited bandwidth for higher-order creation. Technology will not be sufficient until the core of its offer becomes a reduction of stimuli.

The liberation of cognition

Technology has historically progressed through the liberation of the physical (the steam engine, the steel mill) and the biological (vaccines, prosthetics). The logical and inevitable next step is the liberation of cognition, going from moving bodies, to saving bodies, to finally freeing the minds within them. Hum is the teleological conclusion of that sequence.

Right now we are trapped in a physiological paradox. We use tools designed to help, but they maximize our extraneous cognitive load (Chandler & Sweller, 1991), the mental energy spent just operating the interface, leaving almost nothing for the germane load (Sweller et al., 1998), the actual effort of learning, creating, and thinking.

It is no surprise that desktops, laptops, tablets, and phones require endless iteration and a market of accessories to offset our unnatural relationship with them: ergonomic chairs, computer stands, blue-light glasses, note-taking apps, second-brain platforms, productivity reminders. A mature technology should not require layers of secondary products to make it tolerable. It should blend into our nature, the natural inclination to be fluid, to interact socially in the real world, to be truly present.

The machine can assist with the metabolic tax of retrieval and organization, but it cannot determine ends or replace human judgment. The human remains the final author of action.

One might argue that automating the administrative maintenance of our lives risks losing our agency, or black-boxing our own thoughts. But the aim is only to ensure the pen is not so heavy that one forgets what they intended to write: a world where the brain is used for higher-order human activity rather than administrative maintenance, and people spend less time holding, organizing, and retrieving endless context, and more time with thought, creation, and connection.
