How to join the network
Imagine a typical day in 2020: Your personal AI assistant wakes you up with a friendly greeting before preparing your favorite breakfast. During your morning workout, it plays new songs that perfectly match your musical tastes. For your driverless commute to work, it has pre-selected a few articles based on the duration of your commute and what you’ve read in the past.
You read the news and realize the presidential election is coming up. Based on a predicted model that takes into account your previously expressed views and data on other voters in your state, your AI assistant recommends you vote for the Democratic candidate. A pop-up message on your phone asks if you want your AI assistant to handle the paperwork and cast the vote on your behalf. You tap “agree” and get on with your life.
Artificial intelligence is only as good as the data
We are entering a world that is permeated with AI. While personal AI assistants are already becoming a reality, to many it seems inconceivable that we would ever delegate such important civic duties — even if an AI assistant probably knows what’s best for us at any given moment. If fed enough data, an AI assistant could give recommendations that are far more accurate and personalized than anything we’d receive from even our closest friends.
Yet the intelligent potential of machines frequently elicits fear in people. Studies show that 34 percent of people are afraid of AI, while 24 percent think AI will be harmful for society. GWI finds that 63 percent of people worry about how their personal data is used by companies. Our own recent research at the Oxford Internet Institute shows that people hesitate to put their personal lives in the hands of an AI assistant, especially when that assistant makes decisions without providing a transparent reasoning for choosing one solution over a set of alternatives.
There is no need to confuse math with magic. AIs are not operated by small mystical creatures living inside your phones that have a sense of agency and their own agenda. But what we tend to forget is that the seemingly invisible mathematical models that make automated inferences about our interests, locations, behaviors, finances and health are designed by other humans using our pre-existing personal data.
Role of human creators
Much of the current debate on algorithmic culture revolves around the role that humans play in the design of algorithms — that is, whether a creator’s subconscious beliefs and biases are encoded into the algorithms that make decisions about us. Journalism is replete with fears that developers willingly code their algorithms in a way that would permit subtle discrimination against certain groups of people over others — or worse, that technology platforms act as gatekeepers for the information that passes through them. As John Mannes writes, “A biased world can result in biased data sets and, in turn, bias artificial intelligence frameworks.”
The policy makers and pundits advancing this argument tend to misconstrue the evidence for the apparent prevalence of algorithmic biases. They blame the people behind the algorithms, rather than the algorithms themselves. Finding fault in other people is, of course, the natural response, especially if you don’t understand the inner workings of the technologies at hand.
But algorithmic bias rarely originates from its human creators. In the majority of cases, it originates from the data that is used to train such algorithms. And this is, indeed, the real danger of the futuristic scenario described at the outset of this article.
Let’s pause for a moment and recall how machine learning actually works. By applying statistical learning techniques, coders develop computational models that can automatically identify patterns in the data. To accomplish that, the models need to be trained on large data sets to unearth boundaries and relationships in the data. The more data is used to train the model, the higher the predictive accuracy.
In the context of personalized digital applications, these statistical learning techniques are used to create an algorithmic identity for their users, which encompasses several dimensions, such as use patterns, tastes, preferences, personality traits and the structure of their social graph. This digital identity, however, is not directly based on users’ personhood or sense of self. Rather, such inferences are based on a collection of measurable data points and the machine’s interpretation thereof. In other words, the embodied user identity, no matter how complex, is replaced by an imperfect digital representation of itself in the eyes of the AI.
But the AI can only use historically traced data in its computations, which is then used to anticipate the users’ needs and make predictions about the future. This is why neural networks trained on images of past U.S. presidents predicted Donald Trump would win the upcoming U.S. election, after being trained with images of past (male) presidents. Because there were no female presidents in the data set, the AI was unable to deduce that gender was not a relevant characteristic for the model. In practice, if this particular AI were to elect the next president, it would vote for Trump.
These inferences result in increasingly deterministic recommendation systems, which tend to reinforce existing beliefs and practices similar to the echo chambers in our social media feeds. At this point, Jarno Koponen asserts that “personalization caricaturizes us and creates a striking gap between our real interests and their digital reflection.” Meanwhile, the authors of The Netflix Effect explain that personal recommendation systems tend to “steer the user towards this content, thus ghettoizing the user in a prescribed category of demographically classified content.” These aspects become more prevalent over time and it becomes evident why algorithmic determinism may be so harmful.
Fluid identities and change
Our identities are dynamic, complex and contain many contradictions. Based on our social context, we may behave differently and require different forms of assistance from our AI agents — at school or at work, in a bar or in church.
Alongside our default self-presentation, there are many reasons why we may want to enact different identities to differentially engage with various sub-groups in our personal networks. Do we want to make ourselves socially accessible to our entire social network, or do we want to find new untapped social spaces away from the prying eyes of our friends and family? What happens if we want to experiment with different social roles and facets of our identity? As 4chan founder Chris Poole a.k.a. moot says, “It’s not who you share with; it’s who you share as (…). Identity is prismatic; there are many lenses through which people view you.”
Accountability is an important issue here, precisely because it is so difficult to measure and implement on a large scale.
Distinguishing these different layers of self-presentation and mapping them onto various social environments is an extremely challenging task for an AI, which has been trained to serve a unique user identity. There are days when even we don’t know who we are. But our AI assistants will always have an answer for us: It’s who we were yesterday. Change becomes increasingly difficult, and our use patterns and belief systems run the risk of being locked up in a self-enforcing cycle, similar to an algorithmic Groundhog Day.
The more we rely on personalized algorithms in everyday life, the more they will shape what we see, what we read, who we talk to and how we live. By relentlessly focusing on the status quo, new recommendations on books to read, movies to watch and people to meet will give us more of the same things that have previously delighted us.
When your past unequivocally dictates your future, personal development through spontaneity, open-mindedness and experimentation becomes more difficult. In this way, the notion of algorithmic determinism echoes what Winston Churchill once said about buildings: We shape our algorithms; thereafter, they shape us.
How to stop (or slow down) the future
Today, real-world applications of AI are already embedded in almost every aspect of everyday life. But there are two main challenges stopping the potential future outlined in the opening paragraphs.
In terms of technological progress, there is a lack of interoperability standards for data exchange between applications, which prevents radical personalization. To be truly useful, machine learning systems require greater amounts of personal data — data that is currently siloed in proprietary databases of competing technology companies. Those who have the data hold the power. Some companies, most notably Apple and Viv, have started to democratize this power by experimenting with third-party service integration. Most recently, some of the largest technology companies announced a major partnership to collaborate on AI research that benefits the many, not the few. Going forward, this will be crucial to establishing public trust in this technology.
In terms of social progress, there is an implicit aversion to the rapid growth of AI. People are afraid of losing control of their AI assistants. Putting their relationships and reputation on the line for a seemingly marginal improvement in productivity is not something most people are willing to do. Of course, in its early stages, an AI assistant can behave in ways that its human creators might not expect. There are plenty of precedents of failed AI experiments that have diminished trust in narrow AI solutions and conversational bots. When Facebook, Microsoft and Google all launched their bot platforms in 2016, users were disappointed with the limited usefulness, application and customization of the prematurely presented AI technologies.
The lingering fears about the ramifications of AI technology have also been fueled by the many dystopian sci-fi scenarios that have depicted sentient rogue AIs taking over the world. But the future we’re heading toward will be neither Skynet nor Orwellian Big Brother: It is much more likely to look like the hedonic society portrayed in a Brave New World, where technologies maintain the status quote through a regime of universal happiness and pervasive self-indulgence.
New regulatory frameworks
Technologies keep marching ahead, but there’s also hope. The 2016 annual survey of the Global Shapers Community revealed that young people see AI as the main technological trend. What is more, 21 percent of respondents say they support rights for humanoid robots, with this support disproportionately higher in Southeast Asia, where young people appear to have a more favorable attitude toward AI in everyday life.
In Europe, the European Union’s new General Data Protection Regulation could restrict extreme forms of algorithmic determinism by giving users the opportunity to ask for an explanation of particular profiling-based algorithmic decisions. This law is expected to be implemented in all EU member states by May 2018. While this regulation restricts profiling and underlines the pressing importance of human interpretability in algorithm design, it is uncertain whether it will result in any major changes to the prevailing algorithmic practices of large technology companies.
Thousands of algorithmic decisions are made about each of us every day — ranging from Netflix movie recommendations and Facebook friend suggestions to insurance risk assessments and credit scores. All things considered, are citizens themselves now responsible for keeping track of and scrutinizing the algorithmic decisions made about them, or is this something that needs to be encoded into the designs of the digital platforms they’re using? Accountability is an important issue here, precisely because it is so difficult to measure and implement on a large scale.
It is time to chart a sensible path to create transparent and accountable AI to improve humanity’s collective future. Thus, the question we ought to ask ourselves before leaping headlong into the unknown is what do we want the relationship between humans and AI to look like? Rethinking these issues will hopefully allow us to design non-deterministic, transparent and accountable algorithms that recognize the complex, evolving and multifaceted nature of our individuality.
