As algorithms become entrenched into society, the debate about their effects rages on.
In essence, algorithms are sequences of instructions used to solve problems and perform functions in computer programming.
As mathematical expressions, algorithms existed long before modern computers.
While they vary in application, all algorithms have three things in common: clearly-defined beginning and ending points, discrete sets of โsteps,โ and design meant to address a specific type of problem.
And problems we have.
On the one hand, algorithms play the role of prime suspect โ responsible for the recent UK poundโs Brexit-induced flash crash, used for political and informational manipulation on social networks, and part of what Harvard Professor Shoshanna Zuboff calls โsurveillance capitalismโ.
On the other hand, algorithms make modern life easier: they help us find information, detect disease, connect us to friends and family, show us products weโre likely to be interested in, recommend personalised experiences, and direct us around traffic delays, saving us valuable time and money.
Algorithms are everywhere
Much has been written on what algorithms do and how they affect us.
This includes how algorithms secretly control us, what types of information they filter in or out of our social media feeds, and the thousands of calculated outcomes they force on us daily.
This piece isnโt about these issues, or about breaking down the complex nature of how algorithms work.
The relevance of algorithms at the moment isnโt because they are used in Googleโs search, maps, autocomplete, photos, and translation services; Facebookโs news feed and Trends; Twitterโs trending topics; Netflixโs movie recommendations; Amazonโs prices and product reviews; or for predicting hurricanes, creditworthiness, and home and car insurance liabilities.
Itโs not because most computer software and mobile applications are essentially bundled packages of algorithms.
To return to my very first point, algorithms are important because they are the key process in artificial intelligence: decision-making.
AI_gorithms
Algorithms, in a sense, are the โnervous systemโ of AI.
They are the models that underpin machine learning, prediction, and problem solving.
Yet, as many researchers argue, due to their design by humans, algorithms can never be neutral.

As Vint Cerf, co-inventor of the Internet Protocol, Turing Award winner, and Google VP pointed out in a recent speech at Elon University:
โWe need to remember that [AI systems] are made out of software. And we donโt know how to write perfect software โฆ the consequence is that however much we might benefit from these devices โฆ, they may not work exactly the way they were intended to work or the way we expect them to. And the more we rely on [AI systems], the more surprised we may be when they donโt work the way we expect.โ
โThe way we expectโ is key here, because algorithms are a computer-simulated reflection of encoded human expectations.
Engineering memories
Facebookโs famous โOn This Dayโ prompt involves โengineering for nostalgiaโ.
Likewise, Instagram algorithmically sorts its timeline so you โsee the moments you care about firstโ.
The more we, as humans, rely on algorithms, the more our reality becomes encoded with other peopleโs flawed expectations.
As more AI-powered systems come online, this type of calculated bias will permeate every level of our lives โ even our memories and past experiences.
Take, for instance, Google Photos, which uses AI-powered โdeep learningโ to organise peopleโs photos beyond normal metadata (GPS, time, date, lens, etc.).
It uses advanced machine learning algorithms to classify material objects, facial expressions, and emotional relevance.
The robotic โassistantโ even can touch up images, suggest creative filters and create photo albums automatically.
Biased learning, troubled future?
As algorithms โlearnโ more about us through our financial data, location history, biometric features, voice patterns, social networks, stored memories, and โsmart homeโ devices, we move towards a reality constructed by imperfect machine learning systems which try to understand us through other peopleโs expectations and sets of โrulesโ.
Algorithms are the literal manifestation of โplaying by someone elseโs rules”.
For dating app Tinderโs algorithmic โSmart Photosโ matching, the rules of successful engagement on Tinderย are made clear, and enforced on users.
Does this mean that we live inside aย computer simulation?
Iโll defer thatย question to Elon Musk, who has said, โthereโs a billion to one chance weโre living in base realityโ.
Cerf, however, warns that itโs a mistake to โimbue artificial intelligences with a breadth of knowledge that they donโt actually have, and also with social intelligence that they donโt haveโ.
The algorithmic end game, AI, will get better with time, but it will always be flawed.
Even in straightforward applications like a game of chess, algorithms can leave people clueless as to how they arrived at a certain outcome.
Great expectations
Cerf talked about a scenario in which IBMโs โDeep Blueโ supercomputer, playing world chess champion Gary Kasparov, made a move that Kasparov could not understand.
I mean, it made no sense whatsoever. And he was clearly concerned about it, because he thought for quite a long time and had to play the endgame much faster โฆ in the end it turned out it was a bug.
It was just a mistake. The computer didnโt know what it was doing. But Kasparov assumed that it did, and lost the game as a result.
The implications of bias today might result in poor neighbourhoods experiencingย more police brutality because of predictive data modelling.
Tomorrow, it will mean people die when the algorithms controlling self-driving cars are programmed to save the occupants livesย instead of pedestrians.
Bad or good?
Is the social use of algorithms inherently โbad,โ provided they form the basis of โintelligenceโ in AI?โ.
David Lazer, a computer scientist at Northeastern University, is sceptical.
In a recent Science article he said:
The fact that human lives are regulated by code is hardly a new phenomenon. Organizations run on their own algorithms, called standard operating procedures. And anyone who has been told that “itโs a ruleโ knows that social rules can be as automatic and thoughtless as any algorithm.
It does mean that companies, governments, and institutions that employ algorithms, and soon, AI powered deep learning โneural networksโ need to be more transparent in showing us how the algorithms they use might affect our reality.

Given how proprietary algorithms are theย new business model, this is doubtful, even despite current laws preventing algorithms from being patentable.
A recent SSRN piece maintains the need for a โFood and Drug Administration for algorithms”.
Some scholars go so far as to argue that algorithms needย managers too.
According to Cerf:
Itโs a little unnerving to think that weโre building machines that we donโt understand โฆ Not only in the technical sense, like whatโs it going to do or how is it going to behave, but also in the social sense, how is it going to impact our society?
Just like us
Just like us
So, algorithms, the underlying process of decision making in artificial intelligence systems are imperfect, prone to bias, and make unpredictable decisions that impact the future.
