When Everything Is Personalized, Nothing Is Shared

There was a time when culture moved together.

If you grew up in the 80s or 90s, you don't need a sociologist to explain it to you. You felt it. It was in the air.

On summer nights, car windows rolled down and the radio spilled into the street. The same songs drifting from passing cars, from diner speakers, from bedroom windows cracked open to the warm air. You didn't discover music alone. You discovered it with everyone else.

By the time you got to school the next morning, someone was already tapping the beat on a locker.

Music didn't arrive individually. It arrived collectively. It moved through the air.

Television worked the same way.

Thursday nights were sacred in American living rooms. Families sat down together and watched the same stories unfold at the same time. Millions of people across the country laughing at the same moment, waiting for the same punchline.

The next morning, the conversations were already happening.

"Did you see it last night?"

You didn't even have to explain what it was.

Shows like Seinfeld, Friends, The Simpsons, and late night television weren't just programs put on for noise. They were shared cultural rituals. They gave people something to quote, something to bond over, something to carry into the next day's conversations.

Movies had their own rhythm.

When a big film came out, people didn't quietly stream it alone on a Tuesday night. They went to theaters. They stood in line. They planned weekends around it. Entire rooms full of strangers reacting to the same story at the same time.

You could walk into work on Monday and say, "I finally saw it," and half the office already knew exactly what scene you were talking about.

And then there was Friday night.

For an entire generation, Friday night meant a trip to the video store. You would be met with the glow of fluorescent lights. The hum of freezers in the corner. Rows of plastic cases stretching from floor to ceiling. Families wandering the aisles debating what to watch.

Should we go comedy? Action? Something new?

If you were lucky, the movie everyone wanted hadn't been rented yet.

If you're old enough to remember places like Blockbuster or Visions Video, a Brooklyn icon, you'd understand that these places weren't just stores. They were little cultural gathering points. You ran into neighbors in the aisles. Kids argued over the last copy of a new release. Clerks behind the counter recommended movies like local curators.

Later, the ritual evolved but the spirit remained.

People stopped by kiosks on the way home from work, renting DVDs from Redbox machines outside grocery stores. The same new releases cycling through neighborhoods across the country.

We weren't all watching the same movie every night, but we were choosing from the same small cultural shelf.

That limitation created something powerful. It created overlap.

Even video games carried this shared rhythm.

When a new game launched, it didn't just appear in a personalized storefront. It arrived like an event. Does anyone remember the Halo 3 release? Or even going back to just 2013, anyone remember the hype around GTAV? Players lined up outside stores waiting for midnight. Energy buzzed in the air as strangers talked about the same game they had been waiting months for. People comparing consoles, debating which version would be better, counting down the final minutes until the doors opened.

Places like GameStop turned midnight releases into small cultural festivals. Gamers spilling into parking lots clutching fresh copies of the same game, collector's edition statues, and cool memorabilia.

The next day, everyone started from the same beginning.

The same opening scene.

The same first level.

The same discoveries waiting to be made.

Culture had a rhythm then.

It moved through shared channels. It moved through radio stations, television networks, movie theaters, record stores, video stores, and so much more.

We weren't all living identical lives, but we were moving through the same cultural current. There was an invisible thread connecting us. And most of us didn't realize how important that thread was until it slowly began to disappear. Now, people are lonelier than ever before.

When the internet arrived, it didn't break that thread right away.

Early websites still had front doors.

When you opened a news site, everyone saw the same homepage. The same headlines. The same featured stories. If something appeared there, it mattered to everyone.

The early internet still behaved like a public town square. Over time though, the architecture changed.

The technology industry became obsessed with a powerful idea. The idea of personalization.

The reasoning seemed obvious. The internet had become too large. Too much content. Too many videos, songs, articles, and posts for any human being to sort through.

So companies built systems designed to filter the chaos. And the algorithms studied everything.

What you clicked.

What you watched.

What you skipped.

How long you paused before scrolling past something.

From those signals, platforms began constructing individualized worlds for each of us.

No two feeds were the same.

No two homepages were identical.

Instead of showing everyone the same content, the system would show you what it believed you wanted to see.

From a product perspective, it was brilliant.

If the system showed you things you already liked, you would stay longer. You would return more often. You would watch one more video. You would scroll just a little bit further.

At first, it genuinely felt magical.

A movie recommendation that somehow matched your mood perfectly.

A new artist appearing in your music feed that you instantly loved.

A video surfacing that made you laugh before you even knew you needed it.

It felt like the internet understood you.

But while the internet was learning about us individually, something else was slowly eroding. Society was losing the shared layer.

Here is where my perspective complicates the story.

Because I didn't just watch this happen.

I helped build it.

Over the past decade, I've spent my career inside the technology industry building products that run on the very same logic. Systems that analyze behavior. Platforms that collect signals. Software designed to learn what people want before they consciously know it themselves.

We built AI-driven systems that could sift through oceans of data to identify patterns in human behavior. Platforms that could match people, surface opportunities, and optimize outcomes using increasingly sophisticated algorithms.

In travel technology specifically, we experimented with personalized discovery, software that could take someone's interests and location and generate a custom set of recommendations designed specifically for them.

From a product standpoint, it was thrilling work.

You could see the metrics move.

User engagement increased. Retention improved. Recommendations became more accurate. The system got smarter with every interaction, and the industry celebrated this as progress. In many ways, it was.

But somewhere along the way, I started noticing something else.

Every improvement we made at the individual level came with a subtle tradeoff at the cultural level. The better the algorithm understood you, the less it resembled what anyone else was seeing.

Today, two people can sit next to each other on the same couch, open the same app, and see completely different worlds.

Their feeds don't overlap.

Their recommendations don't align.

Their digital environments drift in entirely separate directions.

Instead of one cultural river flowing through society, there are now millions of algorithmically generated streams, each optimized for a single individual.

Personalization didn't just improve recommendations. It fractured the public commons.

The deeper irony here is personalization was supposed to improve discovery. Instead, it often narrows it.

Algorithms are trained to maximize engagement. They learn patterns in your behavior and reinforce the signals that keep you watching, scrolling, and clicking.

You liked this genre of music. So here's more of it.

You watched this type of video. So here are twenty more just like it.

You clicked on this kind of article. So your feed slowly fills with increasingly similar ones.

The system becomes incredibly good at predicting what you will click next, but in doing so, it builds walls around your curiosity. Instead of expanding your world, it refines it and you stop encountering the unexpected. You stop bumping into things outside your preferences. And you stop sharing cultural moments with people who aren't algorithmically similar to you.

Human beings don't consume stories individually.

We process them socially.

We talk about them.

We argue about them.

We laugh about them.

Shared culture creates the connective tissue of everyday life. The casual conversation that begins with "Did you see that?" The joke that works because everyone understands the reference.

Extreme personalization dissolves that layer.

Instead of shared inputs, we now experience individualized lives.

Instead of collective attention, we have fragmented attention.

The internet stops feeling like a town square, and it starts to feel like millions of private rooms. Each of us alone inside an algorithmically curated world reflecting our own habits back to us.

The reality is that none of this happened because someone set out to destroy our shared experiences.

It happened because people like me, builders, product managers, and engineers, optimized for engagement.

Inside product teams across the technology industry, personalization became the obvious lever to pull. If showing someone more relevant content increased retention by even a few percentage points, it was worth doing because it was worth billions.

Each step made sense and each improvement helped the metrics. Taken together, those steps rewired the architecture of the digital town square.

What we gained in efficiency, we lost in collective experience.

There was a time when people lined up together for the same movies.

When families wandered the same video store aisles on Friday nights.

When gamers counted down the same midnight releases.

When millions of people watched the same episode of a television show and talked about it the next morning.

Our culture moved together.

The internet promised to connect us more than ever before, and in some ways, it delivered. However, connection was never just about access to people. It was about access to the same world as other people. A shared floor. Common ground.

I spent years building systems that helped take that floor apart. I was good at it. The metrics proved it. And I think about it every day.

I'm still not sure what to do with that.

What I do know is this: we didn't lose the commons in a war. We traded it away gradually, one optimized recommendation at a time, for a world that finally, perfectly, only reflected ourselves back to us.

We paved over the common ground to build a billion private gardens.

They're beautiful. They're tailored. They're yours.

And you're in them alone.
