It seems incredibly common in works of science fiction that touch upon technological immortality to focus on every possible way that such a technology could go wrong, create problems, or worsen social dynamics.

Among the negative outcomes that have attained trope levels of frequency, off the top of my head, I can name the following:

1. Immortality becomes available only to the ultra-wealthy, allowing them even more power to abuse everyone else, leading immortal people to be antagonists in a pretty generic dystopian plot.

2. Immortality subtly twists the morality of its beneficiaries, causing them to lose sight of "the real meaning of life" according to the author's worldview, and the protagonist usually fights for society to recognize how important death and endings are

3. Immortality causes people to go insane, become monsters, or otherwise utterly lose their humanity (this is more of an extreme version of case #2, but I feel it's distinct in the way a story plays out)

4. Immortality ultimately leads to the extinction of the human species due either to biological effects of the immortality technology in question, or due to cultural/societal shifts that lead people to stop reproducing

I'm sure there are many others that I'd recall if prompted, but my point is that I don't think I can name any science fiction that involves immortality technology that doesn't also decry it as ultimately a harmful development.

Are there any works of science fiction that any of you can think of that do more to celebrate the idea or look forward to it with some optimism?

I can understand why the journey to make this into a film is so convoluted. I'm not sure I've ever read anything so dense and epic. I was always sort of keen to the series, and always thought the worm god was just cool imagery. So I did have kind of an internal motivation to get this far, but now that I'm about to dive into God Emperor, I just feel bad for anyone that called it quits after the first book. Frank Herbert had a lot to say, and faithfully adapting this to any kind of screen, I think, is impossible.

I just finished binging The Habitat, the awesome podcast about NASA's simulated mission to Mars. And I'm feeling the urge to read something along those lines: fiction or true stories and indulge my fascination with space (and things coming from it) and how that relates to contemporary imagination.

Any suggestions?

I've just finished The Sirens of Titan from 1959 (after seeing it recommended here, actually) and something struck me compared to more recent books. A lot of the more technical stuff is kind of hand-waved away. It's not a criticism, just something that stuck out as I was reading. Is this a trend? Do readers demand more details these days? I've read a bunch of sci fi from the 60s until the present day, but I've only really gotten back into it more recently with Sirens.

Perhaps I've read too much Neal Stephenson, who has likely never hand-waved anything away! The Martian also springs to mind, but that's very deliberately focused on the details and keeping it realistic, IIRC.

Once there were three tribes. The Optimists, whose patron saints were Drake and Sagan, believed in a universe crawling with gentle intelligence---spiritual brethren vaster and more enlightened than we, a great galactic siblinghood into whose ranks we would someday ascend. Surely, said the Optimists, space travel implies enlightenment, for it requires the control of great destructive energies. Any race which can't rise above its own brutal instincts will wipe itself out long before it learns to bridge the interstellar gulf.

Across from the Optimists sat the Pessimists, who genuflected before graven images of Saint Fermi and a host of lesser lightweights. The Pessimists envisioned a lonely universe full of dead rocks and prokaryotic slime. The odds are just too low, they insisted. Too many rogues, too much radiation, too much eccentricity in too many orbits. It is a surpassing miracle that even one Earth exists; to hope for many is to abandon reason and embrace religious mania. After all, the universe is fourteen billion years old: if the galaxy were alive with intelligence, wouldn't it be here by now?

Equidistant to the other two tribes sat the Historians. They didn't have too many thoughts on the probable prevalence of intelligent, spacefaring extraterrestrials--- but if there are any, they said, they're not just going to be smart. They're going to be mean.

It might seem almost too obvious a conclusion. What is Human history, if not an ongoing succession of greater technologies grinding lesser ones beneath their boots? But the subject wasn't merely Human history, or the unfair advantage that tools gave to any given side; the oppressed snatch up advanced weaponry as readily as the oppressor, given half a chance. No, the real issue was how those tools got there in the first place. The real issue was what tools are for.

To the Historians, tools existed for only one reason: to force the universe into unnatural shapes. They treated nature as an enemy, they were by definition a rebellion against the way things were. Technology is a stunted thing in benign environments, it never thrived in any culture gripped by belief in natural harmony. Why invent fusion reactors if your climate is comfortable, if your food is abundant? Why build fortresses if you have no enemies? Why force change upon a world which poses no threat?

Human civilization had a lot of branches, not so long ago. Even into the twenty-first century, a few isolated tribes had barely developed stone tools. Some settled down with agriculture. Others weren't content until they had ended nature itself, still others until they'd built cities in space.

We all rested eventually, though. Each new technology trampled lesser ones, climbed to some complacent asymptote, and stopped.

But history never said that everyone had to stop where we did. It only suggested that those who had stopped no longer struggled for existence. There could be other, more hellish worlds where the best Human technology would crumble, where the environment was still the enemy, where the only survivors were those who fought back with sharper tools and stronger empires. The threats contained in those environments would not be simple ones. Harsh weather and natural disasters either kill you or they don't, and once conquered---or adapted to--- they lose their relevance. No, the only environmental factors that continued to matter were those that fought back, that countered new strategies with newer ones, that forced their enemies to scale ever-greater heights just to stay alive. Ultimately, the only enemy that mattered was an intelligent one.

And if the best toys do end up in the hands of those who've never forgotten that life itself is an act of war against intelligent opponents, what does that say about a race whose machines travel between the stars?

I started by reading Banks' scifi, the Culture novels. I fell in love with them, and since I've read every one of those books multiple times, I decided to make the jump into reading his mainstream fiction. I started with The Wasp Factory, and I'd be interested in what you think about that book, if you've read it. If not, go read it! It's good!
