The Most Human Human – Brian Christian ****

This is a brilliant concept well executed, if occasionally missing perfection due to a bit of pretentious twaddle. Of course I am well aware that one man’s pretentious twaddle is another person’s insightful and soul-searching philosophy, so you may appreciate Brian Christian’s musings, but I’d rather he stuck to the meat of the story.
And what a wonderful story it is. Firstly, don’t be put off by the subtitle, A Defence of Humanity in the Age of the Computer – this makes it sound like a Bill McKibben style moan about how it’s time to stop with the technology and get back to nature. This isn’t what it’s about at all. Christian’s central theme is the Turing test – Alan Turing’s idea of seeing how far computers have advanced by asking a human to judge whether there is a computer or a person on the other end of a text message. In particular, Christian introduces us to the Loebner Prize which annually pits the world’s best chatbots against human beings for judges to distinguish in a 5 minute chat.
The story of this challenge, in which Christian was a human subject for the 2009 session in Brighton threads through the book. As Christian looks at ways he might distinguish himself as a human being (hoping to win the prize given for the ‘most human human’, just as one of the bots gets ‘the most human computer’), he explores what human reasoning and thought is about in terms of the development of artificial intelligence and the impact of computers, and particularly pseudo-intelligent computers have on human beings.
The book works best when Christian is dealing with technology and its implications. I first came across a chatbot when ELIZA was installed on our Dec-10 at work in the late 70s and the whole idea of interacting with a computer in conversational speech is fascinating. Similarly, when it doesn’t get too deep into the chess itself, the section where he looks at chess computers and Deep Blue’s victory over Kasparov is also delightful.
Rather less successful are the sections where he spends rather too much time on philosophy and what can come across rather too easily as intellectual waffle. So we get statements like ‘Capitalism presents an interesting gray space, where societal prosperity is more than the occasional by-product of fierce competition: it’s the point of all that competition, from the society’s viewpoint.’ Yeh, right. I also found the author’s ‘bemused with British English, funny old Brits’ tone a little condescending.
Nevertheless, it’s easy enough to skip the worst of the philosophising, which is a relatively minor part of the book anyway, and there is plenty of excellent meat in there for anyone interested in AI, what it is to be human and how one informs the other. Recommended.

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...

Introducing Artificial Intelligence – Henry Brighton & Howard Selina ****

It is almost impossible to rate these relentlessly hip books – they are pure marmite*. The huge  Introducing  … series (a vast range of books covering everything from Quantum Theory to Islam), previously known as …  for Beginners , puts across the message in a style that owes as much to Terry Gilliam and pop art as it does to popular science. Pretty well every page features large graphics with speech bubbles that are supposed to emphasise the point. Funnily,  Introducing Artificial Intelligence  is both a good and bad example of the series. Let’s get the bad bits out of the way first. The illustrators of these books are very variable, and I didn’t particularly like the pictures here. They did add something – the illustrations in these books always have a lot of information content, rather than being window dressing – but they seemed more detached from the text and rather lacking in the oomph the best versions have. The other real problem is that...
