This book is set in a dystopian future where the Boomer cohort has been shipped off to Florida to live on free government provided food drops, and rent is free, because Social Security ran out before 2020 (when the book takes place) and riots forced the government to somehow provide for the huge aging cohort. In the book, the aging Boomers are called pheezers - for "freaky geezers" - many of whom still cling to their youthful rebelliousness (remember this book was written before the 80s - when many of the former hippies switched "allegiance" and became responsible members of society, settling down, settling for "straight world" jobs, educational pathways, and so forth). Some drugs are legalized by the 21st C - and although there's no internet or cell phones in the book, there are startling advances in robotics such that robots can be essentially physically identical with specific individuals and robots have achieved "autonomy" or freedom. The revolt of the robots - deciding to disobey humans - was assisted by the book's protagonist, computer scientist and pheezer Cobb Anderson. The autonomous robots were thereafter banned from Earth and banished to the Moon, where they diligently work on industries/mining that cannot be performed on Earth, subsequently trading their products such as tank-grown replacement human organs, for cash. Thus, there is a trading relationship between Earth and Moon - but the robots in charge of the moon robot colony - called "big boppers" want more,much more. Meanwhile, the worker robot bees on the moon, some of whom are called diggers, dislike their bopper overlords, and a revolution is about to break out that may overthrow the boppers and their nefarious plans.
The book revolves around Cobb's yearning for a new life - immortality. He strikes a Devil's bargain with the boppers - and travels to the colony assured by them that he will be made immortal. His "software" - personality and memories - will be transferred to a replica robot "the hardware." Unfortunately he becomes a robot remote, not exactly an completely autonomous robot like the boppers - and the entire scheme depends on the boppers preserving his "tape" the program, that is his personality and memories, which are encoded on tape. That means his life depends on a thin sliver of plastic - not terribly permanent, despite the illusion of immortality given that his mind/memories have been transferred into a non-aging robot.
There are non-stop scenes of drug use but not that much sexual prurience per se. There is one potentially exceptionally violent scene at the beginning of the sci-fi novel - but the near victim of vivisection managed to escape. I almost didn't bother reading the book, which I regarded as trashy although it did win a prestigious sci-fi prize back in the 80s. It was over-the-top, provocative - it has a distinctly anti-feminist slant. I could "handle" the attitude having grown up in the pre-feminist era. But many people would not enjoy reading a book that doesn't seem to contain one positive portrayal of women (although Annie and Cobb finally seem to be bonding toward the end of th book, and Wendy and Sta-Hi in the end seem to have reached some sort of contentment - both women do not come off positively when they are first introduced - ditto for most if not all of the female characters in the book). It's possible to read the book as a product of its age and laugh but some readers today might be put off by the anti-feminist slant.
The book seemed fevered - although it's well written, by and large - maybe because Cobb and other characters, maybe most of the characters, are either drunk, stoned, or robots - some evil - that Cobb or Sta-Hi (the other protagonist) are trying to dodge, cheat, beat up, evade, escape from, and so forth. The book doesn't lack for action and it's of course a page turner considering the reader wants to find out if Cobb does achieve eternal youth and so forth. There was one particularly hilarious scene when Cobb figures out a sub routine that has been built into him as a robot - what he needs to do to feel drunk (since as a robot, alcoholic beverages don't affect him, nor does he actually require food or drink) and thus "enjoy" himself socially, at parties/dances and so forth. This isn't a particularly pleasant book but as a fast, trashy read, I suppose it's acceptable. The reader does want to find out what happens to Cobb and the other characters - I won't spoil the spectacular ending, so it's up to the reader to find out by making it to the end of the book.
On a less sensationalistic note, it's interesting to read how one author envisioned life 40 years into the future - how society would cope with the Boomers, if Social Security really did dry up. There aren't any gadgets - a notable lack of imagining what would happen with respect to computers - computers are still seen in the book as taking up a room and so forth. The book was written before the advent of personal computers - but there was always speculation about how advanced robots might become. The book, albeit to me at least, rather trashy - and as I said, it does contain one scene of near gratuitous violence plus endless more or less degrading anti-feminist portrayals of women - still, it "works" I suppose as escape fiction. In the book, women are essentially sex objects or drugged out skanks, "mindless" robot vixens or aging virago's. None of the depictions of women are attractive although, as I mentioned above, Ann and (robot) Cobb eventually do form a bond, and Wendy and Sta-Hi seem headed to at least temporarily become a couple by the book's end. Interestingly, there is at least a moment of insight into why otherwise rather cartoon-like Sta-Hi became the way he became - after his father dies and he is talking with (robot) Cobb - Sta-Hi's shell of cool, or detachment (drugged out or straight) is shattered as he and the reader realize that it was his home problems, problems with his parents, that led to his self-destructive behavior. Also, poignantly, his dad, who was always critical of his rebellious son, "loves" robot Sta-Hi since he has assumed at least a superficially "normal" life - unfortunately, that was an illusion and the reality that his actual son never changed, is yet another "insightful" or "pathetic" plot twist. The book otherwise has some nuanced characterization despite characters or robots being often portrayed as cartoons; Cobb - both as human and robot - is definitely multi-faceted. He helped the robots free themselves - but prior to making his deal with the Devil, he can't free himself from the fear of death, and so self-medicates himself with drink daily. He's become an old though majestic man who has taken to sitting under palm trees on the beach meditatively drinking cheap sherry, trying to quell his thoughts of death, and the wife he abandoned. Later, as a robot, he feels he has it made - but his existence depends on a tape running in a mobile computer stored in a refrigerated truck, and meanwhile, robots, including him, are banned on Earth.
This book is a fast, easy read - and for a trashy sci-fi novel from that pre-80s era, I suppose it's fun in a way. I read it in two days - and I'm a slow reader - so a fast reader could probably read it in a few hours. It's not poorly written, and it is interesting or fun to read it mostly. Still, despite the prestigious prize the book won back in the 80s, I can't give it more than two stars.
