It would be easy to dismiss this book, with the reference in the title to Do Androids Dream of Electric Sheep (the Philip K. Dick book) that Blade Runner was (very loosely) based on, as a vanity project by an entrepreneur who has too much spare time on his hands, but it turns out to be an interesting, if sometimes challenging read. I think that James Tagg’s aim was to compare the human brain with what is now and might ever be within the capabilities of an artificial intelligence, and to explore areas like creativity and free will where we may see a difference. And there are times that he does this very well…
