Best Product Building Lessons Don't Come From Tech

If you're building in tech, I can guess your inputs. Hacker News in the morning. Marc Andreessen's blog. Gary Vee or The Diary of a CEO on the commute. Naval's tweets saved in a note somewhere. A Y Combinator founder story you've read three times.

Everyone in your space is working from that same list, then everyone builds the same product and wonders why nothing stands out.

That's tunnel vision, the most common reason good founders sound identical. The ones who break out cut their tech content in half and start paying attention to everything else: fashion, food, fiction, the way a restaurant menu is written.

I'm Daria, a tech and culture analyst who tracks how culture shifts turn into markets. That's what this channel is: tech philosophy for people who are tired of tech content. If that sounds like you, stay. Let me show you how tunnel vision forms, and how to climb out of it.

HOW TUNNEL VISION FORMS Here's what happens when a whole industry reads the same inputs. Everyone optimizes the same metrics. Everyone uses the same design patterns. Every landing page looks generated from the same Figma template, because it was. Every deck follows the same structure. Every product narrative hits the same beats: AI-powered, end-to-end, seamless.

That's a monoculture, and monocultures are fragile. In farming, plant one crop everywhere and a single disease wipes it out. In tech, think the same way everywhere and one market shift makes everyone obsolete at once. On the individual level, that same monoculture becomes tunnel vision: you can only see the road the feed points you down, and everyone else is driving on it too.

I've talked before about the difference between taste and commercial instinct. Taste is what you like. Commercial instinct is understanding what other people will pay for. And that instinct doesn't come from reading about conversion rate optimization. It comes from watching how humans behave in the real world.

Over the 2011 holidays, Brian Chesky read a biography of Walt Disney and got stuck on the chapter about Snow White. He came back and hired a Pixar animator to draw the Airbnb customer journey in fifteen frames. Those frames showed him what the website analytics never had: most of the Airbnb experience happens offline, in the house, after the booking. That reframed what the company built next. None of it came from Hacker News.

Go to a niche perfume shop and watch what happens when the salesperson asks "what do you want to feel?" Go to a museum and notice which pieces stop people and which they walk past. Sit in a good restaurant and pay attention to how the lighting, the pacing, the language on the menu are all engineered to make you feel a specific way. Those are product design lessons, filed under a different name.

The founders I know who have the sharpest positioning almost always have unusually broad inputs. They read fiction. They travel to places that aren't tech hubs. They pay attention to fashion, architecture, food, music, domains where understanding human desire is the entire business.

The ones stuck in tunnel vision have the narrowest inputs: Hacker News, the YC blog, the same five Substacks. They can tell you everything about their architecture and nothing about why a normal person would care.

When AI commoditizes the technical skills that used to set people apart, the advantage shifts to whoever can think differently about what to build and why.

The technical floor rose for everyone. The differentiator now is how well you understand what people need, and how cleanly you can translate something complex into plain language. Building the thing stopped being the hard part. That understanding is a humanities skill, and it's the one that closes deals, wins investors, and builds brands.

Here's the part that should motivate you. In a monoculture, the person with different inputs is a minority of one, and that scarcity is the whole advantage. When everyone reads the same thing, being one of the few who doesn't becomes a structural edge, not a hobby. You get to be the smartest minority in the room: the one who sees what the tunnel hides.

Cut your tech content in half. Replace it with domains that have understood human desire for centuries: fashion, hospitality, fragrance, film, architecture, food, literature. When you read a novel, you're studying how a writer makes you care about a fictional person in fifty pages, the same skill you need to make a buyer care about your product in fifty seconds.

When you study how a house like Hermès builds a brand on restraint and scarcity, you're learning positioning most accelerators never teach. When you notice how a menu is written, the verbs, the framing, the deliberately missing prices, you're watching narrative strategy in action.

Tunnel vision produces builders who all think identically. The ones who break out think differently, and that requires feeding your brain something different. This is also why one clear-thinking founder can out-position a whole committee, which I get into in my video on winning as a solo founder.

In a world where AI can code anything, the edge is understanding humans. That doesn't come from tech Twitter. Read the novel. Visit the museum. Smell the weird fragrance. Your positioning will thank you.
