Person recommendations (with short-form reason[s]):
The Quantum Thief (and I'd assume, the sequel "The Fractal Prince"), by Hannu Rajaniemi - the story dives into topics of personal security, public access memory, intra-stellar colonization,and hitting one or more Singularity events in technology and social splintering. Pacing is quick, detailing incredibly potent, yet giving you time to see parallels in where we are and where we could be, in the not-so-distant future. A wake-up call started decades ago by previous and existing speculative fiction authors and thinkers.
Sprawl Trilogy novels (Neuromancer (1984), Count Zero (1986), and Mona Lisa Overdrive (1988)), by William Gibson - cyberpunk literature that looks at the embedding and transformation-strong elements of technology alongside its own and society's deterministic properties. Puts to task the idea of isolation of the self and the integration of society into a ubiquitous whole through cyberspace, and its physio-socio-psychological backbones. Admittedly, Gibson's writing style can be very sparse/minimalist at times (especially with the more recent literature in the Bigend Trilogy) but the ideas are there and strong, nonetheless.
Heck, anything from William Gibson (including the Bigend Trilogy, in the last decade or so) is a good read.
Last, but not least, is More Than Human, by Theodore Sturgeon. This focuses on the idea of a potential future evolutionary adaptation, where a consummate human being, a gestalt, comes into being through a variety of children - should one be lost or removed permanently, another will be compatible elsewhere in the world. Individually, the children have limited abilities. In tandem as the gestalt (still physically separate), their abilities amplify.
There are more, but their names escape me, which tells me that they're not as crucial or best suited for this post.
