What do you think about artificial intelligence? What do you think of time dilation, the big bang, and other fanciful ideas in theoretical physics? And what do you think about how the world is being run at the moment? The first line in the book is "Just a bit of light reading", and it is certainly not that.
There are "deep dives" into athanasia, the real butterfly effect, a beginning of the universe that doesn't transgress the laws of physics, and as indicated above artificial intelligence and time dilation. You also get a stroll through the main reason why we've never been able to solve any of our biggest problems in "On Revolution". and there are a few other things as well.
This is a compilation of writings I think of as my "Thinking on a Sunday Afternoon" etchings, etching being the process of cutting into unprotected surfaces with acid; but I don't merely do any of it just for the sake of throwing a firebomb. They are all necessary challenges and positions if we are to move forward as a civilisation, as we're about to.
Make sure you read the glossaries in my books even if you know all the words, as I write them with the same flavour as the rest of the book. About 55,000 words.
