Life 3.0 - Max Tegmark ***

I have to confess that my first reaction to this book was not anything to do with the contents, but trying to work out if there was something really clever about the the way the book's title is printed on the spine in white on cream, so it's illegible - would it be, for example, a subtle test of human versus artificial intelligence (AI)? However, that was just a distraction.

Max Tegmark is an interesting and provocative thinker in the physics arena, so I had high hopes for what he'd come up with exploring the future of AI and its relationship to human beings. It's worth explaining that the title of the book refers to three 'levels' of life where 1.0 is 'can survive and replicate' (e.g. bacteria), 2.0 is can design its own software (e.g. us - where 'software' refers to our concepts, ideas and extended abilities such as language) and 3.0 is can design its own hardware, enabling it to transform itself more directly and quickly than our creativity enables us to do.

The book starts with a bit of fiction, which I'm usually nervous about, but it actually works very well, as it's presented more like a non-fiction description of a business development rather than attempting all the quirks of fiction. In it we have a semi-plausible description of how a company that succeeds in producing a self-enhancing AI could take over the world. And this is genuinely thought-provoking.

So, early on, I was convinced I was going to love this book. But unfortunately there is an awful lot of futurology in here (aka guesswork) and like all futurology, Tegmark's can be frustratingly specific about things that we are highly unlikely to be able to predict - though at least he recognises this is the case and points it out. He covers the various ways a super-intelligent AI could develop, whether it would become a rogue, how we'd interact with it... and then plunges on into more and more dramatic speculation, including a chapter that looks forward 'the next billion years and more.' Forgive me for feeling a bit 'So what?' about this.

There is no doubt the whole business of super-AIs is an issue that needs thinking about and discussing - and Tegmark does this in an approachable and engaging fashion. It probably needs reading alongside Nick Bostrom's Superintelligence to get a well-rounded picture, though. It would have helped if it had been significantly shorter - it came across as being long because it was the kind of 'big book' that has to be chunky, and I think it would have been a lot more effective at half its length. One particular section that was ripe for trimming had a long list of scenarios, each of which was then worked through - dull reading, I'm afraid. 

In the end futurology is a bit like being told about someone else's dream. It probably seems fascinating to them, but it's hard to get too excited about it as a reader. Life 3.0 is an interesting book, but feels rather like a pet project, rather than a strong popular science title.

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, ...

The AI Paradox - Virginia Dignum ****

This is a really important book in the way that Virginia Dignum highlights various ways we can misunderstand AI and its abilities using a series of paradoxes. However, I need to say up front that I'm giving it four stars for the ideas: unfortunately the writing is not great. It reads more like a government report than anything vaguely readable - it really should have co-authored with a professional writer to make it accessible. Even so, I'm recommending it: like some government reports it's significant enough to make it necessary to wade through the bureaucrat speak. Why paradoxes? Dignum identifies two ways we can think about paradoxes (oddly I wrote about paradoxes recently , but with three definitions): a logical paradox such as 'this statement is false', or a paradoxical truth such as 'less is more' - the second of which seems a better to fit to the use here.  We are then presented with eight paradoxes, each of which gives some insights into aspects of t...

Einstein's Fridge - Paul Sen ****

In Einstein's Fridge (interesting factoid: this is at least the third popular science book to be named after Einstein's not particularly exciting refrigerator), Paul Sen has taken on a scary challenge. As Jim Al-Khalili made clear in his excellent The World According to Physics , our physical understanding of reality rests on three pillars: relativity, quantum theory and thermodynamics. But there is no doubt that the third of these, the topic of Sen's book, is a hard sell. While it's true that these are the three pillars of physics, from the point of view of making interesting popular science, the first two might be considered pillars of gold and platinum, while the third is a pillar of salt. Relativity and quantum theory are very much of the twentieth century. They are exciting and sometimes downright weird and wonderful. Thermodynamics, by contrast, has a very Victorian feel and, well, is uninspiring. Luckily, though, thermodynamics is important enough, lying behind ...
