A few weeks ago, I caught myself saying something that sounded completely normal:
"I'll just open a website."
Then I stopped for a second. Because that's not really what happens anymore. In fact, I'm not even sure "website" is the right word for most of the things we use today.
Open ChatGPT.
Launch your banking app.
Watch Netflix.
Scroll Instagram.
Push code to GitHub.
None of these feel like websites. They feel more like living systems constantly changing, talking to dozens (sometimes hundreds) of other systems, making decisions, and somehow responding in a few hundred milliseconds.
It's easy to forget how much has changed.
When I first learned how the Internet worked, the explanation was refreshingly simple.
A browser sent an HTTP request --> A web server received it --> The server returned an HTML page --> The browser rendered it --> Done.
This model got me through college, interviews, and even the first few years of my career.
But somewhere along the way, it quietly stopped being true. Not because the fundamentals changed, they didn't. TCP is still TCP. DNS is still DNS. Packets still move across routers exactly as they always have.
What changed is everything we've built on top of those foundations.
Today, opening a "website" might trigger authentication against an identity provider, route traffic through a CDN, invoke an API gateway, fan out requests across dozens of microservices, hit multiple caches, query databases in different regions, call a large language model running on GPUs, collect telemetry for observability platforms, and evaluate security policies before a single pixel appears on your screen.
And the crazy part? Most of us don't notice any of it.
We've become so used to the speed of modern applications that we've forgotten how much engineering is hiding behind something as simple as pressing Enter.
We Don't Really Build Websites Anymore
One of the biggest shifts I've noticed over the last decade is that we're building fewer "applications" and more "platforms."
Take an online banking app as an example.
From the outside, it's one product. You log in, check your balance, transfer money, maybe apply for a loan.
Simple enough.
But behind that login screen, there isn't one application waiting for your request.
There's an ecosystem.
Authentication might be handled by one service. Customer profiles by another. Transactions by another. Fraud detection runs somewhere else. Notifications have their own service. Analytics has another pipeline.
If AI has been integrated, there may even be an internal LLM summarizing customer interactions for support agents.
As users, we experience one product. As engineers, we know it's anything but.
The Internet Quietly Became a Distributed Computer
This is the shift that changed how I think about the Internet. I don't really see it as a network anymore. I see it as one enormous distributed computer.
Not because it's owned by one company. It obviously isn't. But because that's increasingly how it behaves.
Computation happens wherever it makes the most sense. A CDN serves your images from a nearby city. An edge function validates your request. A Kubernetes cluster schedules workloads based on available resources. An AI model might run in a GPU cluster hundreds of kilometers away.
Your data may live in another region entirely. Yet to you, it all feels like one application. And that's remarkable.
Infrastructure Has Become Invisible
One thing I've always found fascinating is how success in infrastructure usually means nobody notices it.
Nobody opens Netflix and thinks:
"Wow, that load balancer did an amazing job."
Nobody finishes a payment and thanks the engineers who designed resilient networking. The better our infrastructure becomes, the less visible it is.
We notice outages.
We rarely notice everything working exactly as intended. That's probably one of the highest compliments infrastructure engineers can receive.
AI Is Just Another Backend Service Now
A couple of years ago, calling an LLM felt experimental. Today, it's becoming ordinary. Some applications call a database. Some call Redis. Some publish a Kafka event.
Increasingly, some also call a language model.
That's a subtle but important shift. AI is moving from being a product to being infrastructure.
I think, in a few years, asking whether an application uses AI will sound as strange as asking whether it uses HTTPS.
It'll simply be part of the stack.
So... What Is the Internet in 2026?
If someone asked me that today, I probably wouldn't start talking about TCP/IP or the OSI model.
I'd say this:
The Internet is no longer just a way to connect computers.
It's a global execution platform.
It's a place where computation moves closer to users, data moves securely across continents, intelligence is becoming a shared service, and thousands of independent systems cooperate so well that we mistake the result for simplicity.
The protocols haven't changed much. Our expectations have. And maybe that's the biggest transformation of all.
I sometimes wonder what developers will call today's Internet twenty years from now.
Just as we look back at "Web 1.0" and smile at how simple it seems, they'll probably look at our cloud-native, AI-powered systems and think they were primitive too.
That's the exciting part of this industry.
The Internet is one of the few inventions that never really finishes evolving.
Every generation inherits a different version of it.
And I think the one we're building right now is the most interesting yet.
