“Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.”
I have a boylike curiosity for the unknown. For what could be, and for what will be. Not ambiguous uncertainties, but rather, within the boundaries of predictable science and reality.
Having read The Singularity (Ray Kurzweil, 2005), What Technology Wants (2010), and Is The Internet Changing The Way You Think? (2011), you gradually paint yourself a clearer picture of the future of everything that relates to technology.
In The Singularity, we learn about the genetics, nanotechnology, and robotics that will eventually become ingrained into our everyday lives, and bodies.
In What Technology Wants, we learn of the “technium,” which is perpetuated by none other than humanity itself. Eventually, technology will evolve itself, without our intervention.
And Is The Internet Changing The Way You Think is the collaboration of 100 great thinkers on the phenomenon called the internet. From science, biology, and engineering, to philosophy, morality, and food for thought.
So where does The Shallows fit in? Right at the intersection of all three — but with a sharper, more uncomfortable question: what is the internet doing to our BRAINS?
How Our Brains Adapted
The Shallows describes how our brains adapted with the onset of new “thought” tools over the millennia, culminating in the internet.
With the map and compass, we were able to visualize the world in a different way. With the invention of the clock, efficiency and productivity were ingrained into humanity. The Gutenberg press in 1440 brought books, knowledge, and the first onset of “information overload.” Then audiograms, radios, and TVs made way for more readily dispersed information, at the cost of distraction.
At which point we step into the internet — “distracted from distraction by distraction.”
What Carr does brilliantly is show that EVERY major intellectual tool reshaped the physical structure of our brains. Not metaphorically — literally. It’s called neuroplasticity — our neural pathways rewire themselves based on how we spend our time. Monks who read manuscripts for decades developed different brains than the farmers around them. And now, we who spend hours scrolling feeds are developing different brains than the book readers before us.
That idea alone should make you pause.
Speed vs. Depth
The internet allows for hyper-information gathering. You are no longer required to read an entire volume of textbooks to find your information. Instead, search engines make it very fast and simple to find the snippets you need.
The speed of information is increased, while the depth of knowledge on the topic is decreased.
Furthermore, we lose the ability for complete immersion brought to us through books. Instead, we receive bite-sized snippets of distractions, whether relevant or not to our pursuit of information.
Various cognitive tests have shown that the consequences of not reading books affect our capacities for various activities.
I felt this personally. There was a stretch where I consumed almost everything online — articles, Twitter threads, YouTube breakdowns — and my ability to sit with a physical book had deteriorated. I’d get restless after 15 minutes. My brain craved the next tab, the next notification, the next dopamine hit. It took deliberate effort to retrain myself into deep reading.
Carr calls this the “juggler’s brain.” We get better at bouncing between tasks, but worse at doing any single task with real depth. And the scary part? Most of us don’t even realize it’s happening.
The Science Behind the Shift
One of the strongest parts of the book is the neuroscience. Carr walks through studies showing that heavy internet users process information differently than deep readers. Their brains show MORE activity in the prefrontal cortex because they’re constantly evaluating links, deciding what to click, filtering distractions.
That sounds like a good thing, right? More brain activity?
Not exactly. All that extra processing leaves LESS capacity for comprehension, memory consolidation, and critical thinking. You’re so busy navigating that you never actually absorb. Like driving through a city so fast you can’t remember any of the streets.
Carr also discusses how hyperlinks — the backbone of the web — disrupt reading comprehension. Every link is a micro-decision: do I click or keep reading? Even if you DON’T click, your brain still had to make that choice, and that tiny interruption chips away at your focus. Multiply that across hundreds of links per day, and you see the cumulative damage.
Adapting to the New
At the same time, we gain and grow the ability for multitasking (although our brains are still infantile at this task). Nevertheless, with the introduction of a new technology, we as humans adapt it very quickly to our wants and needs.
This is no different with the internet, although the consequences of hyper-information should be interesting in the future to come.
That’s what makes this book thought-provoking rather than doom-and-gloom. Carr isn’t saying the internet is evil. He’s saying it comes with a TRADE-OFF — one most people never consciously evaluate. We gain speed, access, and connectivity. We lose depth, patience, and contemplation.
As someone who built a career online, I can’t quit the internet. But I can be more intentional about HOW I use it. After reading this book, I started carving out blocks of time with zero screens. Just a physical book and silence. The difference in focus and retention is night and day.
What Carr Misses
If I have one critique, it’s that Carr leans too nostalgic for the “age of the book.” He romanticizes deep literary reading as the peak of cognition, but I think he underestimates what the internet has unlocked. Self-educated entrepreneurs, independent thinkers, global communities who would NEVER have found each other without the web — that matters too.
The book was published in 2010, and some examples feel dated. Social media was in its early phase, smartphones hadn’t taken over, and AI was barely a conversation. Imagine what Carr would say about TikTok and ChatGPT. The core thesis, though? More relevant than ever.
Final Thoughts
I highly recommend this if you want a philosophical perspective on technology. But beyond philosophy, The Shallows is a genuine wake-up call. It forces you to confront an uncomfortable truth — that the tool you use every day is quietly reshaping the organ you think with.
Pair it with What Technology Wants and The Singularity Is Near for the full picture — both the promise and the price.
5/5 Stars
Thanks for reading.
