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 Language of Mathematics - Raúl Rojas ***

One of the biggest developments in the history of maths was moving from describing relationships and functions with words to using symbols. This interesting little book traces the origins of a whole range of symbols from those familiar to all, to the more obscure squiggles used in logic and elsewhere. On the whole Raúl Rojas does a good job of filling in some historical detail, if in what is generally a fairly dry fashion. We get to trace what was often a bumpy path as different symbols were employed (particularly, for example, for division and multiplication, where several still remain in use), but usually, gradually, standards were adopted. This feels better as a reference, to dip into if you want to find out about a specific symbol, rather than an interesting end to end read. Rojas tells us the sections are designed to be read in any order, which means that there is some overlap of text - it feels more like a collection of short essays or blog posts that he couldn't be bothered ...

Target Earth – Govert Schilling *****

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...
