Two of my close friends and I drove Iceland’s entire Ring Road 1,322 km (in total we drove 2000km).

We saw 𝟏𝟎 waterfalls, 𝟐 volcanic craters, 𝟏 glacier lagoon, 𝟏 glacier we actually walked on, 𝟐 blue ice formations that looked like something rendered by a broken physics engine, 𝟒 villages, 𝟏 city. And somewhere between all of that, a silence so complete it felt physical.

I came back different. Not because of the views because of how small everything felt. In the best way possible.

Also: I breathed. Like really breathed. Reykjavík is the 5th cleanest capital on Earth for air quality (IQAir 2024). I didn’t know lungs could feel that relaxed.

As an ML engineer I find patterns everywhere. Iceland was full of ones I didn’t expect.

394,000 people. That’s it. That’s a mid-sized European city pretending to be a country and (almost) absolutely winning at it. 5th in the world for GDP per capita (~$91k). #1 on the Global Peace Index for 15+ years straight. #1 in gender equality for 14 consecutive years, the only country on Earth scoring above 90% on the WEF Gender Gap Index. Ranked 3rd in the World Happiness Report 2024, yet consistently among the highest in antidepressant consumption globally (based on OECD data measuring daily doses per 1,000 people)

Iceland gets a lot right and it shows. But the full picture also hints that even in high-performing systems, there are deeper, less visible layers shaping wellbeing. Progress is real… just not the whole story. #SmallDataset #MaximumOutput

400k people. All descended from a tiny Viking founding population. Genetic overlap is not a theory it’s a daily risk. So they built Í𝘴𝘭𝘦𝘯𝘥𝘪𝘯𝘨𝘢𝘣ó𝘬, a genealogy app where you literally bump phones with someone before getting close, and it fires an incest prevention alarm if you’re too related. The slogan: “bump the app before you bump in bed.”

I laughed when I first heard this.

Then it becomes clear: it’s essentially a graph traversal problem with real-world consequences, turned into a simple public tool people actually use. A practical solution to a practical constraint, built because it needed to exist.

Around 17.8% of residents in Iceland are foreign nationals. The largest group is Polish citizens (~22,394), making up about a third of immigrants (32.1% of all immigrants as of January 2024).

I’m not Polish, but I live in Kraków. Seeing how large the Polish community is there felt closer to home than expected.

After speaking with locals, it usually comes down to labour demand and established migration networks. I’ve noticed a similar pattern in Ireland too.

Migration is driven less by geography and more by existing connections people tend to move along established links of work, family, and communities, rather than simply to the closest places on the map.

Nobody tells you this upfront, but a road trip there runs on apps.

• 𝘝𝘦ð𝘶𝘳 — weather alerts you don’t ignore

• 𝟣𝟣𝟤 𝘐𝘤𝘦𝘭𝘢𝘯𝘥 — emergency GPS reporting

• 𝘔𝘺 𝘈𝘶𝘳𝘰𝘳𝘢 𝘍𝘰𝘳𝘦𝘤𝘢𝘴𝘵 — nightly KP index checks

• 𝘗𝘢𝘳𝘬𝘢 — paid parking at natural sites

• 𝘌𝘢𝘴𝘺𝘗𝘢𝘳𝘬 — city parking

• 𝘎𝘰𝘰𝘨𝘭𝘦 𝘔𝘢𝘱𝘴 — the routing backbone

What looks fragmented at first is actually a distributed system stitched together through APIs, services, and real-time data streams.

In ML terms, it’s less a single model and more an ensemble each tool handling a narrow task, together producing a robust system. #DataSystems #MLThinking

Route 1. 1,322 km loop around Iceland. Built to connect the country in a single road. Two lanes. 90 km/h limit. Most people plan 7–10 days.

We had everything mapped in Wanderlog as a 7-day itinerary.

By the end of day 2, extreme wind hit and lasted a full day strong enough that the next day had to be cancelled entirely. That forced us to compress the trip into 6 actual driving days.

After speaking with locals (and checking conditions), this is a known constraint of the system:

• in the south, ~28 m/s winds (gusts up to 40 m/s) can close roads completely

• in the north, even ~15 m/s combined with snow can do the same

Statistically, in April, a noticeable share of Ring Road itineraries (~15–30% according to traveller reports and seasonal closure patterns) experience at least one full-day disruption due to weather, which directly reduces the likelihood of completing a 7-day plan exactly as scheduled.

We still completed the circle, just under a tighter execution window than planned.

Vatnajökull is massive in a way that’s hard to process in numbers alone. Around 7,700 km² in size (roughly 8% of Iceland), with ice up to ~950 m thick and an average thickness of ~380 m. Beneath it sit multiple active volcanic systemsat least seven, constantly interacting with the ice above.

It’s also changing fast. The glacier has been losing mass steadily over recent decades, with thickness decreasing by roughly ~1 meter per year in many monitored areas (and total ice loss accelerating in warmer periods).

In simple terms: it’s Europe’s largest ice mass, but not a static one.

I walked on it. Touched ice that started forming long before humans left Africa. It didn’t feel like a landmark it felt like time compressed into something physical.

Some things aren’t really “data points.” They’re just hard to fit into any model.

Iceland sits directly on the Mid-Atlantic Ridge. The North American plate drifts west, the Eurasian plate east. The result: the land slowly expands by ~2 cm per year.

Over deep time, this is not static it’s divergence. The system is continuously updating, just at a geological learning rate.

Nothing is fixed. Not even the ground.

The tallest building in Reykjavík is the church. Hallgrímskirkja. 74.5 meters. Designed in 1937, construction started in 1945, finished in 1986. 41 years. In tech we complain about a two-week sprint running long.

The city runs on 100% renewable electricity 70% hydro, 30% geothermal. 90% of central heating comes from geothermal hot springs piped directly into buildings. Switching to geothermal saved Iceland an estimated $8.2 billion between 1970 and 2000 alone. And the air WHO PM2.5 compliant, top 5 cleanest capital globally.

I kept taking deep breaths just because I could. #GreenCompute #SustainableInfrastructure

Simple: they import almost everything. Remote North Atlantic island, 400k people, small market, oligopolistic retail, high import tariffs. Groceries run roughly double what you’d pay anywhere else in Europe. A coffee can hit €7. A basic dinner for two? Budget €80 minimum.

The exception is energy. Geothermal and hydro make electricity and heating almost free by comparison. So the cost model is clear: you pay for everything physical, almost nothing for power.

2.26 million tourists visited in 2024. That generated $4.2 billion roughly $440 per tourist per night. Tourism is now ~40% of Iceland’s export earnings. They didn’t market themselves. They have volcanoes, glaciers, and northern lights. And that’s enough. #CostModeling #BusinessIntelligence

This trip was a dataset. A weird, beautiful, humbling one.

Genealogical graphs solved by a phone bump. A glacier formed before our species existed, melting in real time. A nation of 400k people quietly topping every human development index while the rest of us scale to billions and still can’t figure it out.

I left Iceland thinking: small doesn’t mean limited. Sometimes it means everything’s just closer to the surface. The data. The ground. The ice. The people.

• Thanks to my friends for making this happen—we drove every kilometer together. Worth every one. ✈️📊

• Thanks to Nori, our guide in Reykjavík, for sharing so much about the city and its history I highly recommend his walking tour https://citywalk.is/

• Thanks to my tattoo artists (Icelandic, Polish), who gave me a more grounded, almost underground perspective of Iceland in our conversations

• Thanks to all the Greeks we met along the way sharing stories about Iceland, travel, and places worth going next made the experience even richer

• Thanks to the Icelandic people for their openness and hospitality wherever we went

And finally, thanks to Iceland itself for such a unique experience I came back calmer than I left
