Blindsight
By Peter Watts
Hard Science Fiction
(actually writing that out loud kind of shifted my views, first contact novels were always cool)
Blindsight was a new experience for me. I had not read an abundance of hard sci-fi (hard sci-fi is defined as science fiction with a specific attention to detail directed towards making sure it is realistic and logical) or sci-fi in general, and even less of books about aliens (probably only one other I can name off my head). Holding this in mind I regardless found Blindsight to be personally enjoyable.
Now, what is the plot of Blindsight? Alien's first contact doesn't really tell you much. Well.
Sometime in the future humanity has casually perfected cryosleep travel (if you want to go anywhere in space, you are frozen to stop aging briefly because space travel takes a very, very, very long time), uploading your mind to the internet, AI, and integrative cybernetics, and so on.
A living translator with multiple personalities, each of which are physically independent of one another and confined to separate parts of the brain
A human computer, who prizes metal over flesh, who acts as a biological tool compartment.
A pacifistic soldier in the bleak event that war is declared.
A synthesist (don't worry, I didn't know what that was either), with half his brain missing whose role is to recontextualize and reframe the world around him into easy-to-understand chunks. (Also, this is our main character).
Upon arriving at the signal, the crew finds a massive empty asteroid (I think it was an asteroid at least, had lots of tunnels) orbiting an uninhabitable planet being skimmed by large drones. And thats all I will say. Because Blindsight is part of a series, and one of the main parts of the book is figuring out the mystery of how first contact is going to be established when there is no one there.
The rest of the review will be me covering some cool details that I thought were interesting while reading through the novel. There are mild SPOILERS, but nothing too significant; primarily just worldbuilding.
2. Heaven is a cyber-hellscape. Heaven is a digital simulation that people upload their brains into when they are about to die, allowing them to live eternally in an isolated digital afterlife that they completely control. This leads to theological and political divide as people paying for an afterlife or circumventing death is a divisive topic.
IF YOU ARE READING THE BOOK PROBABLY DON'T READ PAST THIS POINT
I like how they are a hive mind (kind of like a brain), where each individual alien is the equivalent to a synapse whose goal is to propagate and remain as efficient as possible. They are pretty much just a sentient nervous system. Each one stores all of their knowledge in themselves and when they're ready to share information they just tear each other apart and pass the information down to to the rest of them. Strangely, the aliens slightly mimic humanity in their views on efficiency; both aim towards the idea of progress and being the most efficient one can be above all else. In fact, the aliens become hostile to Earth and initially went dark because they were exposed to language, media, advertisements, and thought these were useless forms of communication that did nothing but waste energy. Why would another organism want to waste another organisms energy? Parasitism, viral infection, sabotage. Ergo, humanity is a threat.
I also like how the aliens physically hide from the crew. As their whole body is just a nervous system, they just move really, really fast for a split second whenever a person's eye is stuttering. The human eye doesn't see one continuous image when seeing, it sees a bunch of snapshots all blended really close together to create sight. The aliens simply "jump" whenever one of these snapshots are taken; in short, it allows invisibility but only for one person who is looking at it because different pairs of eyes are taking snapshots at different times (If any of this is wrong, I apologize. I'm not an expert on eyes and their function.). I think this is pretty cool. That's it. Just wanted to divulge how cool I thought the aliens were.
Thanks for listening to my ramble!
