The best novels about mind uploading

I fell in love with Stross’s book based on a single line: “The wreckage of an incredible meal is scattered across the tables around her.” I never forgot that evocative sentence and the vivid imagery it inspired. This book directly invokes the biggest concepts in cosmological futurism, like Matrioshka brains: star-powered computerized uber-brains.

This book has it all. I enjoyed the space-themed perspective on the singularity, which is less focused on the happenings on Earth and more on a space-faring civilization as the full scope of the singularity comes to pass. I particularly appreciated the utilization of a laser sail to transport an uploaded crew in a spaceship far too small for conventional humans, a concept that only works in the context of mind uploading.

This book is now widely recognized and has received a two-season arc on Netflix. Nevertheless, I read it before the Netflix transition and found it to be a wonderful presentation of certain aspects of mind uploading, most notably the ability to survive capricious bodily death due to easily removable artificial brains (essentially mind uploads).

I also appreciated the depiction of interstellar travel via beamed brain state data files, although in a faster-than-light fashion necessitated by the story’s parallel narratives on worlds scattered throughout the cosmos. Frankly, the most enjoyable aspect of it is the style of writing, which has a seedy portrayal of a future society that laces sci-fi with both cyberpunk and noir overtones.

This book has two concepts that have stuck in my memory for years: the uplifted space-faring squid and the end-of-universe-scouring of astronomical bodies into perfectly smooth spheres. How many stories take the notion of the future to its logical extreme by showing the cosmos literally withering away countless eons downstream?

This book directly shows such a far-flung world, an endgame to which almost no science fiction story ventures. Mind uploading occurs in the novel in the far future of humanity, less so in much of the novel’s storyline in the near future, but I included it in this list because the book itself is fantastic and Baxter genuinely leans into a future in which mind uploading is an inevitable and expected outcome.

I specifically recall the scene in which a mind-uploaded character is being subjected to interesting psychological experiments, such as having his neural processing slowed, sped up, and even completely halted without feeling any awareness of those changes.

This book is a fascinating philosophical deep dive into the relationship between functionalism and consciousness. The other thing I was personally drawn to was the story’s use of cellular automata and artificial life since these areas of computer science have been passions of mine even longer than mind uploading.

This book feels different from the other four. It predates the others by several decades and wears its unique era in Clarke’s voice from a previous generation.

The most astounding thing about Clarke’s depiction of the future is how prescient he was, writing in the 1950s: a city-wide supercomputer that runs all of society, a population whose minds are stored in the computer’s data banks with a subpopulation rendered physical at any time in the form of uploaded people who live different lives over and over again.

How did Clarke envision these concepts becoming commonplace four decades later in the 1990s? This book is worth reading just to stand agape at Clarke’s premonitions of a technological society that embraces notions of mind-uploading that are far more commonplace nowadays.
