My own book may be crap, but I am certain, when such an imbalance in profitability as the one I have just described emerges, between photojournalism and selfies, that it is all over. This is not a critical judgment. I am not saying that the photos of Pol Pot are good and the selfies are bad. I am saying that the one reveals a subject and the other reveals an algorithm, and that when everything in our society is driven and sustained in existence by the latter, it is all over.
Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them.
The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern.
In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
I’ve had this (semi-vague) idea that I want to write about what keeps us excited to work on Are.na, on the occasion of its 10th (yes 10th) birthday. While writing generally is a tricky process for me, this subject motivation is even trickier.
In turning this subject around in my mind, and thinking about all the people and things that have been influential, I have some idea about what keeps us going.
I started thinking about all the other important “nodal points” (I don’t know what else to call this) of people, places, books, albums, websites, etc. that all played a part in shaping who I am as a person and what I think is important. These points are a combination of seeking things out myself and getting a recommendation that felt like it was actually for me. A mixture of both passive and active knowledge acquisition.
ultimately, it's the totality of those “nodal points” that indicate one’s own unique perspective. It doesn’t matter if you specifically sought out the nodal point or not, it’s the recognition that counts. When you encounter a piece of life-changing information (no matter how large the change part is), you are simultaneously discovering and creating “yourself,” becoming incrementally more complete. Your perspective (where your gaze is directed) is made up of a meandering line through these points. Learning (or maybe some precursor to learning) is a lot about developing the intuition to recognize when something you find in the world is going to be a nodal point for you.
Over the course of 10 years of using Are.na, I have fully adopted the view that any piece of information can be important to a person given the right context. And on Are.na, pieces of information can be arranged in infinite varieties of contexts – their respective meaning shifts as the proximate information shifts. In other words, the more connections a block has, the more opportunities it has to be a nodal point.
One question that is still hard to answer after 10 years of working on Are.na is “what is the long term vision?” This is difficult for a few reasons.
One reason is that we have to calibrate our definition of long term with the person who is asking the question. Are.na is a lifelong project. Our ideal outcome as a company is not becoming the next Facebook (god forbid), it’s becoming the next Nishiyama Onsen Keiunkan, a hot spring hotel in Japan, and one of the world’s oldest businesses (founded in 705 AD).
It often feels like Are.na itself has its own needs and desires—that Are.na has its own personal intuition. And that we (you and I) are figuring out what it wants to be together. We (the organization that works on Are.na) have a very defined sense of how things should be done and why building Are.na is important, but we try not to be overly dogmatic about what exactly it should evolve into.
…We’ve long had the sense that it’s possible to cultivate an experience on the Internet that is more calm, thoughtful, and introspective. And we’ve long had the view that this is possible not from a technology-oriented approach, but from an approach that is more soft, more personal, and more intuitive.
…If we are the blade, what is the shield? I think it’s speed: The dominant model for online platforms (especially social platforms) is speed and scale at all costs. But to us, growing Are.na in the correct way is more important than growing it quickly.
