被算法操控的生活

  马克斯・泰格马克和他的朋友们有权利坐下来展望人工智能的未来，但是我们应该实事求是地看待他们的讨论，认清他们对话的本质。这只是一群或多或少具有相同社会经济背景、相似教育背景和工作经验的富人在对科幻小说般的事情高谈阔论而已。当我和奥勒・格斯特伦讨论这些问题时，我也陷入了同样的困境，我们都是科学家，戴着科学家的有色眼镜看待问题回到现实世界，在未来很长一段时间内，唯一类似人类的智能形式只会是人类自己。我们真正面临的问题是，究竟是用已有的算法来造福广大民众，还是用算法满足少数人的私欲？二者择一，我很清楚自己的选择。

  ‘Basically, if you assume people are lazy then you can predict most of their behaviour.’‘The more options people are shown on sites like these, the fewer options they look at.’ When we are shown too much information, our brains decide that the best thing to do is just ignore it.

  The other major source of ‘spooky’ adverts is retargeting: we simply forgot that we searched for a trip to the Algarve, but your web browser has remembered and fed this information to TUI, who are now offering you a room in their finest hotel. We are subjected to such vast quantities of advertising and spend such long periods of time staring at our phones and screens, that now and again adverts appear to have read our minds.

  ‘Can a computer ever understand us better than a human?’The data scientist says it can.One day, he says, we might fall in love with a computer that understands us better than our partner.

  No matter how good a regression technique is, without data a model can’t work.

  In fact, it is often humans that see things in binary states of black and white. We make statements like ‘he is too stupid to understand’, ‘she is a typical Republican’ or ‘that person shares everything on Twitter’ almost reflexively, without thinking about the lack of subtlety of our judgements. It is humans who see the world in binary.

  We are clicking our personalities into Facebook, hour after hour, day after day. Smileys, thumbs ups, ‘likes’, frowns and hearts. We are telling Facebook who we are and what we think. We are revealing ourselves to a social media site in a level of detail that we usually reserve for only our closest friends. And unlike our friends – who tend to forget the details and are forgiving in the conclusions they draw about us – Facebook is systematically collecting, processing and analysing our emotional state. It is rotating our personalities in hundreds of dimensions, so it can find the most cold, rational direction to view us from.humans think about other people in just a small number of dimensions – age, race, gender and, if we know them a bit better, personality – while algorithms are alread...

  Over the past 50 years, sociologists and psychologists have used PCA to categorise our personalities, our societal values, our political views and our socio-economic status. We like to think of ourselves as multi-dimensional. We see ourselves as complicated individuals with many different sides to our characters. We tell ourselves that we are unique, that we are shaped by the millions of unique events that occur during our lifetimes. But PCA can reduce those millions of dimensions of complexity to a much smaller number of dimensions which can be used to put us in boxes or, to use a more appropriate visual metaphor, to represent us as a few different symbols. PCA tells me that I can, more or less, see my friends as clusters of circles, squares and crosses.

  The real world has real problems and it is our job to come up with real solutions. There is so much more complexity to every problem than just making calculations. The social media giant was the best place to start investigating how algorithms classify us.Are mathematicians making the world a better place?

  In the future, society might demand that we link up our search, social media and health data, in order to get a complete picture of who we are and why we get ill.We are designing algorithms to recognise faces, to understand language and to learn our music tastes. We are building personal assistants and chatbots that can help you fix your computer. We are predicting the outcome of elections and sporting events. We are finding the perfect match for single people or helping them swipe through all available alternatives. We are trying to provide the most relevant news for you on Facebook and Twitter. We are making sure that you find out about the best holiday breaks and cheap flights. Our aim is to use data and algorithms as a force for good. Algorithms are used everywhere to help us bette...

  Many of them conduct their studies in their spare time, using their skills as programmers, academics and statisticians to find out how the world is being reshaped by algorithms. All the big Internet services – including Google, Yahoo, Facebook, Microsoft and Apple – build up a personalised picture of our interests and use these to decide what adverts to show us. Even when we use our settings to tell Google which adverts we do and don’t want to be shown, it makes its own decisions about what to show us. These black boxes were influencing the information we saw and making decisions about us, while we were left unable to work out how these algorithms operate.algorithms were making arbitrary decisions about us, often based on dubious assumptions and inaccurate data.
