Can computers think? No, they can’t actually do anything
Computers don’t actually do anything. They don’t write, or play; they don’t even compute. Which doesn’t mean we can’t play with computers, or use them to invent, or make, or problem-solve. The new AI is unexpectedly reshaping ways of working and making, in the arts and sciences, in industry, and in warfare. We need to come to terms with the transformative promise and dangers of this new tech. But it ought to be possible to do so without succumbing to bogus claims about machine minds.
What could ever lead us to take seriously the thought that these devices of our own invention might actually understand, and think, and feel, or that, if not now, then later, they might one day come to open their artificial eyes thus finally to behold a shiny world of their very own? One source might simply be the sense that, now unleashed, AI is beyond our control. Fast, microscopic, distributed and astronomically complex, it is hard to understand this tech, and it is tempting to imagine that it has power over us.
But this is nothing new. The story of technology – from prehistory to now – has always been that of the ways we are entrained by the tools and systems that we ourselves have made. Think of the pathways we make by walking. To every tool there is a corresponding habit, that is, an automatised way of acting and being. From the humble pencil to the printing press to the internet, our human agency is enacted in part by the creation of social and technological landscapes that in turn transform what we can do, and so seem, or threaten, to govern and control us.
Yet it is one thing to appreciate the ways we make and remake ourselves through the cultural transformation of our worlds via tool use and technology, and another to mystify dumb matter put to work by us. If there is intelligence in the vicinity of pencils, shoes, cigarette lighters, maps or calculators, it is the intelligence of their users and inventors. The digital is no different.
But there is another origin of our impulse to concede mind to devices of our own invention, and this is what I focus on here: the tendency of some scientists to take for granted what can only be described as a wildly simplistic picture of human and animal cognitive life. They rely unchecked on one-sided, indeed, milquetoast conceptions of human activity, skill and cognitive accomplishment. The surreptitious substitution (to use a phrase of Edmund Husserl’s) of this thin gruel version of the mind at work – a substitution that I hope to convince you traces back to Alan Turing and the very origins of AI – is the decisive move in the conjuring trick.
What scientists seem to have forgotten is that the human animal is a creature of disturbance. Or as the mid-20th-century philosopher of biology Hans Jonas wrote: ‘Irritability is the germ, and as it were the atom, of having a world…’ With us there is always, so to speak, a pebble in the shoe. And this is what moves us, turns us, orients us to reorient ourselves, to do things differently, so that we might carry on. It is irritation and disorientation that is the source of our concern. In the absence of disturbance, there is nothing: no language, no games, no goals, no tasks, no world, no care, and so, yes, no consciousness. [Continue reading…]
