Finally got around to reading something relevant to the thread theme. Is Speaker-to-Animals the most iconic space cat in science fiction?
Teleportation. Reactionless drives. Anti-gravity. Impenetrable stasis fields. Alien megastructures.
Very early on it becomes clear this is not hard science fiction. I should've had a bad time, but thankfully Larry Niven is not a poor writer. He has wit and humor and doesn't take his setting too seriously. His characters constantly bicker and quip like in a Marvel movie, which helps, as I probably couldn't stand them if they were serious all the time. His science isn't all bad, he understands the way spaceships move in space and when he breaks physics he usually does it on purpose, not by mistake. I spotted a few exceptions, such as the good ole just use a mirror to deflect a military grade laser trope, with the added bonus of colored fabrics apparently being good enough to stop lasers of the same color. Bussard ramjets make an appearance, an idea largely discredited now, but in fairness he couldn't have known. The story has an undercurrent of anxiety about overpopulation, which is so 20th century.
After meeting exotic aliens like kzin and puppeteers, I found it a bit disappointing that the inhabitants of Ringworld are just humans. I'm not sure if this is meant to be some kind of an inversion of a trope, as the story treats the two alien companions of Louis as allies that can be empathized with, rather than as a strange other. It's not your usual type of first contact story.
Oh, do I even need to explain what a Ringworld is? After all, by this point, it's a concept permeating popular culture. This is the book that famously ripped off Halo.
Larry's approach to inviting suspension of disbelief reminds me of the old salesman's tactic where you place an expensive piece of merchandise next to something even more ridiculously unaffordably expensive, so that the less expensive product on the shelf appears more reasonably priced in comparison. He has a character explain a Dyson sphere first, before he starts talking about the Ringworld, I guess in the hopes that the reader would now believe the idea of a solid ring made of a nearly indestructible material 2 AU in diameter isn't totally batshit insane. Sorry, it still is.
The variable blade is a clear precursor of a light saber. Strangely, after it's introduced it never really becomes a plot point again. No, sorry, I meant to say Larry Niven ripped off Star Wars. Does he have any imagination?
I felt the quality of the writing drops a bit toward the end, perhaps due to the author rushing to wrap things up. I especially cringed at the insistence of keeping Louis' big plan a secret, with his companions, including the fierce and proud cat beast and the cowardly puppeteer who usually wants to make sure that everything is perfectly safe before committing to anything, just going along for days with no one questioning why they're pinning everything on a plan this one guy simply refuses to explain. Especially when it clearly has elements that could go catastrophically wrong any time killing everyone and/or destroying their only hope of escape. I get they were not professional explorers but at this point I felt like I was just watching a bunch of bumbling retards, or more accurately, plot automatons slaved to the author's desire to move things forward while maintaining the ending "surprise", which to me wasn't much of a surprise at all as I guessed the nature of the mystery object in question pretty much the moment it was first described early in the book. After all, this non-surprise would have been spoiled if the team sat down like adults and discussed both the strong points and weaknesses of the plan before doing anything.
An enjoyable sci-fantasy adventure with a mildly disappointing ending, with elements of mystery that sometimes land and sometimes fall flat. It's not terrible but I'm a bit puzzled by its lofty reputation.
