I'm looking for sci-fi books grounded in plausible, near future realism which dive deep into portraying a transhumanist world and the consequences of humans diverging into new species and exploring new types of consciousness.
Preferably something that goes beyond the basic cyberpunk stuff of regular humans who have one or two metal bits stapled to their head. Something that goes further and shows how humans might use technology(cybernetic, genetic, pharmaceutical, or other kinds) to change into wildly new forms and species with new kinds of cognition, consciousness, etc and the divisions that might form between these new transhuman species as a result.
Most transhumanism in sci-fi only portrays slightly modified people who are still basically normal humans, but immortal, or with cool prosthetics, or more athletic or intelligent or whatever. That's not what I'm looking for.
Blindsight by Peter Watts does a good job of portraying transhumanism in the way I'm looking for by focusing on how hyperspecialized transhumans require an intermediary to communicate meaningfully with normal biohumans. Although this novel doesn't actually focus much on showing what the society on Earth looks like.
Dune also does a good job at showing how alien and surreal transhumanism can get, but I'm looking for something more grounded in realism and near future Earth.
Any suggestions?
