Since the very first sharpened stone, every tool, invention, or piece of technology conceived by humankind has helped to overcome previously insurmountable limits. Yet every advance has brought its shadow. The ink of the printing press gave wings to thought, but also to the flames of the Inquisition; the looms of the Industrial Revolution created both wealth and misery; nuclear energy lit up cities and set the sky ablaze over Hiroshima. The networks woven by the internet connect us, but they also ensnare. Today, we enjoy information and entertainment that would have been unimaginable just a decade ago. In return, the indiscreet algorithm now predicts our desires before we even know we have them.
Some philosophers of science have argued that the tools created by humans do not possess inherently positive or negative effects on the way we think and act—it all ultimately depends on how we use them. Yet beyond how we employ technology, the very act of using it already entails a transformation of our brain. The compass, regardless of its practical benefits, altered our internal cognitive processes. All forms of modern technology—spectacularly distilled into that small rectangle of light we call the mobile phone—offer us unparalleled efficiency, vast learning opportunities, and instant social connection… but it seems to charge our brain a fee. What are the consequences of today’s hyperconnectivity on our neurological architecture?
On the one hand, there is the dilemma of memory. We used to remember phone numbers, important dates, addresses. Now we rely on our devices and, without meaning to, we generate a kind of digital amnesia. On the other hand, there is the problem of fragmented attention. The constant interruptions triggered by mobile devices activate a pattern of divided focus: our brain jumps from one task to another without fully engaging with any of them. Efficiency declines, and in a way, our cognitive resources become depleted, affecting our ability to sustain deep and focused concentration.
Moreover, digital interaction fosters instant gratification: with every notification, with each new piece of content, we receive brief but potent flashes, just enough to ignite the habit. Gradually, the mind becomes accustomed to fleeting stimuli and begins to favour immediacy over depth. Tasks that demand stillness, patience, and sustained attention—such as reading, studying, or critical reflection—become increasingly arduous. We are more equipped than ever to process and react to stimuli, but at the expense of our capacity for deep understanding and critical reasoning.
The next step in the revolution may not be so much digital as cognitive: learning to manage the changes that our devices have brought about. In this digital journey, the challenge no longer seems to be the machine but the brain.
