Atomos, the Greek root of atomic, means irreducible. The cover of Lawrence’s book and the drive of his arguments, provide a modern quest for irreducible human nature in the 21st century context of emerging computer intelligence.
Much of this quest, weaves reference to the origins and growth of machine intelligence, including Alan Turing’s vision and achievements, with a wide-angled view of the enmeshment of science and culture through the 20th century until the present. With many examples ranging from fateful decision-making in the Allied D Day Normandy landings to Neil Armstrong’s landing on the moon, Lawrence builds a picture of what humans have sought in gathering data for making vital decisions and how mathematical ‘machine intelligence’ came to assist. His arguments come into strong thematic focus in the final chapter, ‘Trust’.
Lawrence makes it clear that a key feature of evolving AI is that it has become enormously fast in gathering information, leaving human cognition far behind. With mastery of a defined set of rules, Deep Blue beat Gary Kasparov, the world chess champion, and later the world’s best Go player, Lee Sedol. Its increasing success and power have transfixed, and also alarmed us. Yet, already, as Lawrence points out, it has dutifully woven itself into manifold areas of our practical lives.
“Machine intelligence is pervasive and integrated with all aspects of our lives. It has military implications, but it also has implications for our health, agriculture, cities, art, science, engineering, media and businesses. As a pervasive technology it has implications for who we are as human beings and for human society.” p.354
Yet, by contrast with the power of AI, Lawrence shows that a key distinguishing feature is that it is not existentially embodied as we are. He quotes from a series of lectures by Baroness Onora O’Neill (2002), entitled, ‘A Question of Trust’. She notes that a set of processes, however clever, do not have a social stake in the way individual humans do.
“Processes cannot be betrayed to the Stasi by their husband, they cannot understand what it is like for a child to lose a parent, or a parent to lose a child…”p.352.
Lawrence argues that humans are not only embodied, but our conscious and biologically embedded intelligence, is vastly richer and more-wide ranging than computer intelligence. He makes the distinction between reflective and reflexive intelligence. The former is our conscious cognition, while the latter is embodied in multiple semi-conscious judgments and co-ordinations. He compares the latter to an ecosystem, in which human neurology from head to toe, including our immune system and autonomic balances, our whole intelligent insertion into our environment, has been tested and refined by millions of years of evolution.
There is a further, deeper layer of intelligence embedded in the environment itself. Post-industrial humans have been ignorant of the delicate balances of nature, built up and established prior to the birth of human life. Only now are scientists and governments awakening, in the midst of climate change, deforestation, and extinction of species, to the depth and complexity of the planet.
The three-fold image that Lawrence builds, proves helpful to rightly place AI in the greater scheme of life.
At the thinnest layer of life, we encounter the virtual, mathematical world of AI. Its strength is powerful rapidity, able to draw on and mimic human language and imagery, but incapable of being involved in, or accountable to suffering or empathetic relations which are embedded in culture and what Wittgenstein called ‘forms of life’.
In the middle realm, are human beings with embodied, biological intelligence. Moment by moment apprehension and judgment that we all make, are run through vast networks of lived experience.
“One aspect of the atomic human is the richness and variation in the culture that sustains us.” But he adds,
“Relative to the ecosystems around us, the nuances of our culture pale in comparison to the complexity of the wider earth. However fast the computer is, its ecosystem is the least rich.” p.355
The deepest layer of intelligence is held by our planet, upon which we all depend and from which we have evolved.
Lawrence’s achievement in this exposition is to explain the development of AI and its successful roles to date, while at the same time attempting to rightly position it in our human culture, a vital task.
In early chapters Lawrence mentions Wittgenstein’s connection to Bertrand Russell through development of logic, yet flowing through the book is an echo of the tenor of Wittgenstein’s later notes entitled ‘Culture and Value’ (translated by Peter Winch). Many of these notes point to technical civilization threatening the deeper layers of human culture. One seems particularly emblematic of the commendable striving of Lawrence’s humanistic book:
“Perhaps one day this civilization will produce a culture. When that happens there will be a real history of the discoveries of the 18th, 19th and 20th centuries, which will be deeply interesting.” (Culture and Value-64e)
