The term artificial intelligence has been with us since the 1950s, when the Turing test was conceived and introduced. The Turing test is designed to “test a machine's ability to exhibit intelligent behaviour equivalent to, or indistinguishable from, that of a human”.
From that, we shaped the initial definition of AI as “a machine’s ability to execute cognitive actions usually connected to humanlike actions”, whereas the actual term artificial intelligence was coined by the American scientist John McCarthy in 1956.
To me, that definition is only partly valid today as, in the interconnected networking paradigm, we have a broader scope than single, isolated machines to deal with. We have networks and, hence, we have neural networks, enabling AI to cross the boundaries of a single machine into a networked system, allowing for even more intelligence to be harnessed and excelled upon. A distinction very worthwhile contemplating.
That said, not only has the world evolved since the 1950s, but I have also noticed in my line of work that there are multiple perspectives of what AI is – and isn’t.
Zooming out for a moment, I’d like to add that, as with any given topic we wish to take on, we first need to establish what we mean. We need to define it. Properly. Over the years, I have encountered numerous – and quite confusing – definitions of some well-known concepts: digital, digitalisation, transformation, innovation, disruption, robotisation, to mention a few, and now – artificial intelligence.
In the case of defining AI, I have noticed that some link it to automation, and some to robotisation. Some define it from a more technical viewpoint, equalling it to machine learning or deep learning. Yet others include areas of application such as computed vision, biometrics or speech recognition.
Here is the thing. Until we have established a clear understanding of what we mean, and what we wish to get out of using the technology, we are not able to act adequately since our perceptions of something (subject, object or topic) will shape our actions and thereby determine the way we respond to it.
So, what is your definition of AI?
