When broken down, algorithms are just a set of steps to produce a desired outcome. Growing up I learned how to solve the Rubik's cube, spoiler alert, there is no magic sequence, it’s just a bunch of algorithms used at different points. Therefore, I was introduced to algorithms at a young age, but the difference between the algorithms for a Rubik’s cube (R U R’ U R U2 R, one of the first algorithms you learn on a Rubik’s cube) and "the algorithm", or more accurately networks of tens or thousands of algorithms that make up your TikTok feed are as similar a human is to a single cell organism. Both are made up of cells but one is infinitely more complex. Please keep in mind throughout the rest of this I will be referring to algorithms either singular or plural, there is rarely ever a single algorithm, it is almost always a large web of algorithms that make up what we interact with on social media news feeds or in our amazon suggested products.
Filterworld starts off with the story of the “Mechanical Turk” a large "mechanical" device that fooled people into thinking it was an automatic chess playing machine, however the whole time it was just a person crammed inside the device making the moves playing chess. The Mechanical Turk has been used as a metaphor for emerging advanced technology that turns out to be done by humans and the author argues “Algorithmic recommendations are the latest iteration of the Mechanical Turk: a series of human decisions that have been dressed up and automated as technological ones, at an inhuman scale and speed”. A recent example was earlier in 2024 when the cashier-less amazon go stores were revealed to indeed not be monitored by a sophisticated computer vision system that could track what you picked up and put into your cart. Instead, it was one thousand Indian workers who were watching the camera feeds and tracking what customers were picking up and putting in their carts. Technically they weren't lying when they said it was AI but instead of Artificial Intelligence it was A (lot of) Indians.
I enjoy the reference to the Mechanical Turk because it hits on the point that at the end of the day algorithms are human created. It can be easy, especially with the recent introduction of AI, to think that algorithms are a black box that no one understands how they work. However, this isn’t true, while at times I’m sure webs of algorithms can become extremely complex, at the end of the day algorithms are designed to create a specific outcome or with a specific goal in mind. A clear example of this is Twitter (X, but I will be referring to it by its dead name). Twitter was purchased by Elon Musk in 2023 and since then he has implemented many changes, I will spare most of the details, but many users have noticed Elon’s own tweets appearing much more frequently in their "For You" feed. If we didn’t have the words from the engineers themselves, it would have been a safe assumption to conclude the outcome/goal of twitter’s algorithm was to recommend Elon’s tweets more frequently. I will make no conclusions on if this was a beneficial change as this is not about the politics of the platform or Elon, it is just to illustrate that algorithms are manipulated by humans to produce outcomes they desire. In this case, Elon Musk wanted his tweets to reach more people, and since he owns Twitter, he was able to task his engineers to change the algorithm to make that happen.
Filterworld is also a unique choice of title for this book because on the surface it may be hard to understand how that relates to algorithms. I just told you algorithms are a set of steps that produce a desired outcome. A set of steps that produce an outcome can also be how you describe filters. Let’s say you want to find an apartment, you first select what city, how many bedrooms and bathrooms, the square footage, and price range, these filters will help you reach a desired outcome. As I mentioned at the start of the article the author describes Filterworld it as his word for “the vast, interlocking, and yet diffuse network of algorithms that influence our lives today”, additionally he notes the significant impact on culture and it is distributed and consumed.
The other half of the title of the book Filterworld is “How Algorithms Flattened Culture”, from a glance at a bookstore this second part of the title also may not be the easiest to decipher. When talking with my family about the book they questioned what the author means by “flatness”. Kyle Chayka describes this as “homogenization but also a reduction into simplicity: the least ambiguous, least disruptive, and perhaps least meaningful pieces of culture are promoted the most”. I was going to make a convoluted reference to a specific moment in late 2024 pop culture, but it may just be more impactful to relate the authors words above with some things you yourself have noticed changing over the years and becoming staler and not like they used to be. Whether that is movies, TV shows, music, books, fashion, etc. While some of the feelings can be attributed to nostalgia, the motivations for some creators have changed over time to prioritize popularity over the art itself and the algorithms have rewarded that at the cost of quality.
