To prevent the evolution of "sophisticated organic civilizations" a "machine culture" leaves weapons satellites in orbit around once promising planets." Rev. Jerry L. Parsons, FR #65 (March 1984): 25, source for the initial entry, and quote. See Across the Sea of Suns III.9, pp. 146-47 in 1984 Timescape edition (which you use for all our page citations here).
Long entry for a very important novel raising early, seriously, and at length issues of not just machine intelligence (A.I.) but machine life (Artificial Life, A.L.).

From the Internet Speculative Fiction Database, linked above:
Synopsis: A human team exploring a planet which emits copies of old radio programs from Earth finds a race of organic beings apparently bioengineered to emit radio signals, but then is attacked by a seemingly dormant ancient alien orbital installation. A few years after this event, Earth becomes mysteriously infested with monstrous sea creatures which attack and destroy any human ships, but also another seemingly friendly species, who appear to be the adults of the destructive creatures, and help a few humans survive both the monsters and the destructive nuclear war that breaks out worldwide. The interstellar probe has now reached another planetary system, where they find signs of life deep in an ocean covered with kilometers of ice, with another ancient alien installation in orbit. A team member with prior experience of alien artifacts on Earth theorizes that an ancient machine intelligence has placed similar weapons around any planet that might develop organic intelligence to destroy it if it appears, the wreckage of one such being what he found on Earth, which allowed humanity to escape destruction; and that the machine aliens reacted to the contact with humans by tracing their origin to Earth and transporting the destructive aliens there. After the alien orbital weapon cripples their vessel, the survivors devise a way to attack and disable it, whereupon they find the original interstellar ship which brought the mechanical aliens to the system, and they resolve to use it to bring the fight to the aliens throughout the galaxy.

This is a difficult but important book, very important for the study of the human/machine interface, usefully complicating the idea of life with opposing "organic life" to "machine life." Not just machine intelligence, but machine life in a (paradoxically) biologically meaningful sense.
For this and additionally (and more specifically), see:
Nigel Walmsley being offered a job doing "Heavy foundry work" where he'd be "socketed": "They hooked you into the big machines, connected you with hip and knee and elbow and wrists, the delicate electronic interface matching directly to your nerves. And you sensed the machine, you felt the machine, you worked the machine, you served the machine, you were the machine." Nigel declines: "No." (I.1, in 1984 Timescape edition, p. 13).
Thinking about his work on "Slotsleep" devices — for hibernation — Nigel thinks of the "alphabet jumble of organizations — […] they were machines not people" (I.5; p. 38).
Doing an autopsy on "EM" (Electro-Magnetic) aliens Nigel is introduced to the idea that "spherical shells" could be better for energy absorbing than "the swarm of ropes we've got in our gut," and in general the EM's having "a lot better engineering" than we have, including having the equivalent of "a transistor, a lot of 'em" (III.5, pp. 104-06).
In a "telepresence" scene (our use of a more recent term), Nigel is "on," remotely, an alien planet describing how "the feedback loops lace him into the machine dynamicals better and better" — and Nigel comes to enjoy "the deft sure movement of the servos" and the experience generally (III.5, pp. 114-15). Cf. and contrast empowerment in enveloping servo-mechanisms in such works as AVATAR and the several works linked there, some more relevant here than the biological (appearing?) avatars in AVATAR.
In the Ra and Isis system Nigel observes the EM aliens and comes to understand the behavior of the EM aliens:
They seek volcanoes for food not for warmth. The lava flows down thousands of meters of mountainside, a hot metallic conductor falling in the strong magnetic fields of Isis, cutting the magnetic field lines and generating currents, electric fields, a vast circuit that cannot close easily because the rock around the lava is inert, a poor conductor, and so the electrical current builds in the lava flows, cutting across more field lines, gathering energy until it strikes a seam of metal-rich ore and suddenly the circuit can close, it is shorted, the vast currents runs through the blue-green rock layers, seeking return channel to the top of the mountains complete the loop, blind current following Faraday's remorseless law. As the currents find their way through the metallic corridors […] the EMs tap into an outcropping of the seam and drink of the rushing river of electrons, sucking in to charge their capacitor banks, feasting, spilling it into radio waves as they celebrate the renewal of themselves. They soak from the land itself the high-quality energy, without having to undergo the slow and painstaking process finding chemical foods, digesting them, transferring molecular binding energy into stored electrical potentials. [***] The energy coming from the orbital angular momentum of the Isis-Ra system, an eternal energy source, endlessly churning the crust of Isis, subducting metals in the soil and then in turn thrusting them, molten, from the mouths of the mountains, the iron-rich rivers […] seeking the center of the planet again [… producing] a vast and perpetual generator changing gravitational energy to useful electrical forms, an energy which no other creature than the EMs can tap, giving them the edge they need on this sluggish rust world, making possible their radio eye and with it a steady survey of the sky, searching for an answering strum of electromagnetic song, a vigil that they had that had gone on now for aeons without machines or computers or the army of mindless servants men have made to help them. Here these creatures had harnessed the grinding workings of the planets themselves, all to survive, all to call a plaintive note into a still and silent sky. (III.7, pp. 130-31)
Minor point, but Nigel's working "on the Jurkey" (V.2, page 208) is a direct nod to the "Chicken Little" source of grown meat in Frederik Pohl and Cyril Kornbluth's The Space Merchants, which see.
As the trip continues, more people on the Lancer ship "worked in Interactive mode, computer-linked to the vast machines that churned in Lancer's bowels. After a while "They thought differently" and "when they wished to learn something, they exchanged cerebral templates with someone who knew the material" (VI.2, p. 230). Cf. motif of machine-assisted learning in such works as Haldeman's The Forever War.
Nigel "sealed into the sum-sense pod" for a kind of VR psychotherapy (VIII.2) and in preparation "for the Sleepslots" (VIII.7). Later in the novel, Nigel "is servo'd to a thing like an eel that swims and flips and dives into a howling dance of protons. His body lies three hundred meters away, safely behind slabs of rock. But the eel is his, the eel is him. [...] In a blinding orange glare Nigel swoops, feeling his power over the servo'd robot grow as he gets the feel of it" (VI.3, p. 234; see also VIII.3, p. 297).
Nigel identified as "enough of a mechanistic thinker [...]" that, probably most immediately in context, he sees Mind and body as one thing (VI.4, p. 239).
Dialog between Nigel and Carlotta —
[Nigel:] "Machines can evolve, just as animals do." [Carlotta:] Look those things we found, orbiting god-awful […] worlds. Sure, they're automated artifacts. But intelligent? Self reproducing, okay. the time needed to make a really smart entity is —" [Nigel:] "Enormous. Granted. We haven't dated most of those worlds […]. They could be billions of years older than earth." "There was the rub. It was difficult to think of what the Galaxy might be like if organically derived intelligence was a mere passing glimmer, if machine evolution dominated in the long run. The ruins Lancer and the probes were finding seems to say that even societies [... that] colonize other worlds could still be vulnerable […]." (VI.4, p. 246)
Dialog among Nigel Carlotta and Nikka —
[Nigel:] "A Watcher will appear around every world where technology is possible […]. They're cops […]. * * * The robots which were shuffling ice at Wolf 359, for example. No Watcher there, because those patient little fellows are an early form of a machine society. Give 'em a few million years of exposure to cosmic rays, a shortage of materials — they'll evolve. Become a member of the club" […] A network of ancient machine civilizations/ They sent the Watchers." (VI.4, p. 250)
"[P]reparing Nigel for the Sleepslots. Shutting him down [...]." "This was what it was like to be an analytical thing, a machine, a moving matrix of calculation, without chemical to glandular ties" (VIII.7, p. 316, 317).
"The great powers all acted the same [...] and it was easier to think of them as big machines that do what they were designed to do rather than as bunches of people" (IX.1, p. 339) — Note that they are headed toward a disastrous nuclear war so they can get to Judgment Day without Skynet or other conscious and malicious machines.
"The Skimmers[,]" life-forms aliens have introduced to the waters of Earth, "hated the machines that had intruded into their home waters. They had learned about them in the long years of voyaging, moved and fed and poked at by things that hummed and jerked and yet had no true life. Not like life that arose from nothing at all, flowering wherever chemicals met and sunlight boomed through a blanket of gas" (IX.2, p, 352).
Nigel, apparently near death and exploring on his own, spots what he initially thinks are EMs"
Not the huge-headed beast he knew. These were slim, tall, graceful in their grave pacing.
Not EM's, not without the radio-dish heads and the awkward carapace that housed the reworked guts.
These were what the EMs were before.
Before the asteroid rain crushed their biosphere. Before they had to remake themselves into something the wWatchers would pass as perhaps machinelike.
"The Watchers were patient […] and knew more of life than men [knew], knew that it could arise wherever energy passed through a chemical environment and drove the processes that made a mockery of entropy, building up order." Most basically "that [even] at a moon's core, nuclear isotopes collected and sputtered and delivered up their warmth to an ocean of elemental matter, and that was enough" for the inception of life (IX.4, p. 379).
Nigel feels
"INERT. DRIFTING. DISCONNECTED from glands and the singing of blood. Awake but not fully aware.
This was how it might be for the Watchers, and the machine and labyrinths that had made them. Patient and calculating, in principle like life in their analytic function, and in the laws of evolution that acted equally on silicon-germanium as it did on DNA, yet they were not fully in the world of as life was, from the crusted bonds of molecular law, did not thrive in the universe of essences — as the Snark had put it, groping for a human term to tell what it felt like forever beyond its cybernetic grasp — and thus feared and hated the organic beings that had given birth to them it died in in turn.
Or perhaps the words hate and fear could not penetrate the cool world where thought did not stir hormones to love or flee or fight, where analysis reigned and built with bricks of syllogism a world that knew the hard hand of competition but not the organic wholeness that came out of enduring mortality. (X.5, p. 384-85)
The machines, though have positive points: (1) they are loyal to one another, and (2) respect and try to maintain their mechanical diversity.
Nigel speculates, which well may be the view of the author — and is a minor motif in this novel — that "The machine cultures had been in the universe a long time, since the first inhabited world committed nuclear suicide. They were an accidental fact of the universe, arising from the inappropriate response of organic beings" (X.7, p. 394).

Experimental fiction pursuing a rigorous empiricism, including one describing minutely the exploration of what may be a vast cylinder. Arthur D. Hlavaty suggests Samuel Beckett's How It Is (French Comment c'est 1961, full English translation 1964).[7] Erlich recalls a more sanitized, built environment, possibly in a work in dialog with Beckett's How It Is; both works would be relevant for different monologs by the protagonist.
Cyberspace as a VR in which one can seem to fly in Cyberpunk works such as Neuromancer and its descendants.
