Artificial Communication - Elena Esposito ****

Sometimes, you read a book where the content is so interesting and important that it's necessary to disregard the fact that it's not a great piece of writing - this is such a book. The fundamental point being made here is that the concept of 'artificial intelligence' is mislabelled. What a smart speaker or AlphaGo or an autonomous vehicle does has nothing to do with intelligence. Intelligence implies understanding - but the algorithms of AI have no understanding of the data they handle. Instead, sociology professor Elena Esposito suggests, what they are capable of is artificial communication.

We see this most clearly with those smart speakers, or voice assistants on smartphones. I ask Siri a question and she responds - it is a form of conversation, and one that mimics intelligence, but it is based on something totally different from understanding. The same can be said when using a search engine. These are no longer mere indexes - we ask them questions and they reply with answers. But even in a less obvious application, there is a form of conversation going on between the AI and its environment - enabling it to carry out actions that in a human require intelligence, but don't in the way that the software/hardware is implemented.

For me, this is absolutely fascinating - a necessary adjunct to reading about AI to understand its limitations and how to deal with those limitations better. That's why the book gets four stars. Unfortunately, though, it would have been a lot better if Esposito had taken on a co-author. The text is highly repetitive, making some points repeatedly, and that's in a book that's already short at 111 pages before hitting the notes.  It is also frustratingly vague. Many of the aspects of AI it talks about are covered in a broad, high level fashion without clear examples. The writing sometimes has the feeling of the kind of soft (indeed, squidgy) social science paper that was the target of the Sokal hoax.

The worst example is a chapter on data visualisation and visual text analysis which does not contain a single specific example. The only illustration in the whole chapter (indeed, pretty much the only one in the whole book) is a picture of a house to illustrate the high bandwidth of a picture. But in a chapter crying out for some actual visualisations (and more of an explanation of what digital text analysis actually does with clear examples) there is no assistance for the reader.

Frustrating in some ways, then, but a book I still heartily recommend because the topic itself is so illuminating, even if the approach taken sadly isn't. We can't expect every academic to be a great writer - many aren't - but when that's the case, a much better book could have been produced if they had paired up with a professional.

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 ...

Pagans (SF) - James Alistair Henry *****

There's a fascinating sub-genre of science fiction known as alternate history. The idea is that at some point in the past, history diverged from reality, resulting in a different present. Perhaps the most acclaimed of these books is Kingsley Amis's The Alteration , set in a modern England where there had not been a reformation - but James Alistair Henry arguably does even better by giving us a present where Britain is a third world country, still divided between Celts in the west and Saxons in the East. Neither the Normans nor Christianity have any significant impact. In itself this is a clever idea, but what makes it absolutely excellent is mixing in a police procedural murder mystery, where the investigation is being undertaken by a Celtic DI, Drustan, who has to work in London alongside Aedith, a Saxon reeve of equivalent rank, who also happens to be daughter of the Earl of Mercia. While you could argue about a few historical aspects, it's effectively done and has a plot...

Amazing Worlds of Science Fiction and Science Fact: Keith Cooper ****

There's something appealing (for a reader like me) about a book that brings together science fiction and science fact. I had assumed that the 'Amazing Worlds' part of the title suggested a general overview of the interaction between the two, but Keith Cooper is being literal. This is an examination of exoplanets (planets that orbit a different star to the Sun) as pictured in science fiction and in our best current science, bearing in mind this is a field that is still in the early phases of development. It becomes obvious early on that Cooper, who is a science journalist in his day job, knows his stuff on the fiction side as well as the current science. Of course he brings in the well-known TV and movie tropes (we get a huge amount on Star Trek ), not to mention the likes of Dune, but his coverage of written science fiction goes into much wider picture. He also has consulted some well-known contemporary SF writers such as Alastair Reynolds and Paul McAuley, not just scient...
