When will machines be smarter than us? It\u2019s the most common question students ask me. My answer is \u201cThey already are\u201d. Smart machines can already do things that humans could never do; a spreadsheet can calculate a table of numbers in a fraction of a second, for example. There\u2019s a lot of hype around artificial intelligence. The tech industry in particular is always looking for something new, even when it\u2019s not new, so in a sense AI is just a new label for technology.<\/p>\n
That said, at the beginning of this century, computer scientists made a big breakthrough in being able to build much deeper neural networks, with more layers in between them. Because we\u2019re building faster and faster computers, people argue that we\u2019re effectively building intelligence, and soon there\u2019ll be no limit to what this intelligence can do. It plays to Western fears about creating something which then destroys the creator \u2013 from ancient Greek mythology, where Pygmalion fell in love with one of his sculptures which then came to life, through to Frankenstein and the Terminator.<\/p>\n
This doesn\u2019t mean we shouldn\u2019t be worried about AI, but we need to reframe the question: instead of focussing on what this technology can do, we should be focussing on what we should do with this technology. That\u2019s why I ask my students to think about the ethical implications of\u00a0whatever they go on to build. For example, the government is moving its services online, but that doesn\u2019t mean everyone can access those services. We need to ask, is it going to discriminate against people, or lock some people out from certain benefits that they might otherwise have had?<\/p>\n
For my PhD I built a robot and conducted experiments to observe how people interacted with it. What I learned was that if the machine nature of a robot is overt, then humans are able to see it as a mechanism, and therefore better understand its purpose. For example, what\u2019s the economic transaction that\u2019s going on? Who\u2019s benefiting from this robot? How much of the benefit that\u2019s being derived is ours? By making technology transparent, it\u2019s less likely people
\nwill be deceived by it.<\/p>\n
I think there are dangers in continually trying to optimise life because we learn when we search and explore for ourselves. For instance, when tech companies replace search functions with recommendation engines, we start to defer to the technology, which could then weaken our own decision-making capabilities.<\/p>\n
AI also has huge implications for human to human contact. Take sex robots, for example. As we build smarter machines there will be a tendency to start to treat them like people, but conversely this could mean we start to treat people like machines. Or the self-scanning supermarket checkouts might be more efficient, but for people who live alone, talking to another human at the checkout might be the only contact they get in a day. So it\u2019s important to explore what the implications are of optimising human contact to the extent where relationships are replaced by transactions.<\/p>\n
Guiding principles around AI already exist, but we really need standards of professional behaviour that are enforceable, like the norms that we have in other areas, such as genetic engineering. And that\u2019s a new attitude in this area, because technology is all about being disruptive. To put it simply, just because you can do it, it doesn\u2019t mean that you should.<\/p>\n
