A hard sci-fi milestone – for better or worse

3 stars

If I had read this book 10 years ago (or even 5), it might have felt like a revelation. Reading it today feels like entering a cul-de-sac.

Looking around it helps me understand a couple of things, though: How hard sci-fi works (or why it doesn’t), for one; what makes transhumanism so repulsive (and profoundly boring), for another.

Hard sci-fi is more science than fiction – or at least it tries to be. Equipped with enough knowledge about math, physics or whatever science of choice to go above the reader’s head, but not enough to enter scientific discourse itself, hard sci-fi is, I think, best understood as playing with potential scientific theories without ever having to spell them out. As such it’s not so much an exploration of a few wild ideas but the exploitation of some narrow ones.

This can be very interesting (in Egan’s case, the idea of …

Very creative hard scifi

4 stars

A good but demanding read with great concepts for science fiction, but at times it does feel like the author tied several great short stories into one trench coat novel. Mind you, that's not a bad thing, just something to consider.

The first chapter can be seen as its own small and can be read on the authors blog, which i highly recommend! It sets the tone of the story pretty well by introducing a level of "techno-babble" that will be present at other parts of the book. You have the choice to read it and attempt to fully comprehend it or skim through it with the necessary understanding to catch the intent. If you want to understand the techno-babble or broaden your understanding, the author even supplies visual guides and very short explanations on his website, easily findable from the link for the first chapter. www.gregegan.net/DIASPORA/01/Orphanogenesis.html

SciFi can't get harder than this

No rating

I've seen it described as "diamond-hard SciFi", it might even be an understatement. It starts off being confusingly abstract. After ~15% it gets more coherent, slightly more corporeal, though never entirely so.

Even through its abstract and detached universe, it revolves around modern issues of reality, subjectivity of perception and even memetic reality bubbles.

There's a lot to get from this, provided you can keep your mind clear enough to absorb the weirdness of it all.
