Free Rifters 4 - Blindsight by Peter Watts

observer effects to a minimum. This time I permitted myself a small breach. "The static's nice. I could do without the screeching."
    "Are you kidding? That's the music of the spheres, commissar. It's beautiful . Like old jazz."
    "I never got the hang of that either."
    He shrugged and squelched the upper register, left the rain pattering around us. His jiggling eyes fixed on some arcane graphic. "Want a scoop for your notes?"
    "Sure."
    "There you go." Light reflected off his feedback glove, iridescing like the wing of a dragonfly as he pointed: an absorption spectrum, a looped time-series. Bright peaks surged and subsided, surged and subsided across a fifteen-second timeframe.
    Subtitles only gave me wavelengths and Angstroms. "What is it?"
    "Diver farts. Those bastards are dumping complex organics into the atmosphere."
    "How complex?"
    "Hard to tell, so far. Faint traces, and they dissipate like that . But sugars and aminos at least. Maybe proteins. Maybe more."
    "Maybe life? Microbes?" An alien terraforming project...
    "Depends on how you define life , eh?" Szpindel said. "Not even Deinococcus would last long down there. But it's a big atmosphere. They better not be in any hurry if they're reworking the whole thing by direct inoculation."
    If they were, the job would go a lot faster with self-replicating inoculates. "Sounds like life to me."
    "Sounds like agricultural aerosols, is what it sounds like. Those fuckers are turning the whole damn gas ball into a rice paddy bigger than Jupiter." He gave me a scary grin. "Something's got a beeeg appetite, hmm? You gotta wonder if we aren't gonna be a teeny bit outnumbered."

    Szpindel's findings were front and center at our next get-together.
    The vampire summed it up for us, visual aids dancing on the table: "Von Neumann self-replicating r-selector. Seed washes up and sprouts skimmers, skimmers harvest raw materials from the accretion belt. Some perturbations in those orbits; belt's still unsettled."
    "Haven't seen any of the herd giving birth," Szpindel remarked. "Any sign of a factory?"
    Sarasti shook his head. "Discarded, maybe. Decompiled. Or the herd stops breeding at optimal N."
    "These are only the bulldozers," Bates pointed out. "There'll be tenants."
    "A lot of 'em, eh?" Szpindel added. "Outnumber us by orders of mag."
    James: "But they might not show up for centuries."
    Sarasti clicked. "Do these skimmers build Fireflies? Burns-Caulfield?"
    It was a rhetorical question. Szpindel answered anyway: "Don't see how."
    "Something else does, then. Something already local."
    Nobody spoke for a moment. James' topology shifted and shuffled in the silence; when she opened her mouth again, someone indefinably younger was on top.
    "Their habitat isn't anything like ours, if they're building a home way out here. That's hopeful."
    Michelle. The synesthete.
    "Proteins." Sarasti's eyes were unreadable behind the visor. Comparable biochemistries. They might eat us .
    "Whoever these beings are, they don't even live in sunlight . No territorial overlap, no resource overlap, no basis for conflict. There's no reason we shouldn't get along just fine."
    "On the other hand," Szpindel said, "Technology implies belligerence."
    Michelle snorted softly. "According to a coterie of theoretical historians who've never actually met an alien, yes. Maybe now we get to prove them wrong." And in the next instant she was just gone , her affect scattered like leaves in a dust-devil, and Susan James was back in her place saying:
    "Why don't we just ask them?"
    "Ask?" Bates said.
    "There are four hundred thousand machines out there. How do we know they can't talk?"
    "We'd have heard.," Szpindel said. "They're drones."
    "Can't hurt to ping them, just to make sure."
    "There's no reason they should talk even if they are smart. Language and intelligence aren't all that strongly correlated even on Ear—"
    James rolled her eyes. "Why not try , at least? It's what we're here for. It's what I'm here for. Just
