Beyond the Tattered Veil of Stars by Mercurio D. Rivera (Asimov’s SF, March/April 2020) begins with an introduction (supposedly Chapter 63 of a book) which shows a group of lizard-like creatures called “The People” taking part in a purification rite at Verdant Cove. They are praying for clean air (and we learn that they have a climate warming problem similar to Earth’s).
The next section opens with a journalist called Cory arriving at the laboratory of Milagros Maldonado, an old flame, to interview her about her research. Milagros says she has a big story for him and, as she used to work for a multinational R&D company called EncelaCorp until leaving on bad terms, Cory is hoping for something juicy that will help save his precarious blogging job. However, before Milagros agrees to talk she insists on locking his “retinal readers” (which means he can’t publish the interview without her permission). Then she talks instead about the Simulation Hypothesis (which posits that humanity is living in a simulated or virtual universe), before going on to say that she has created a simulated reality where life on Earth took a different evolutionary path:

“Every change to prehistory resulted in the rise of a different apex form of intelligent life. In this version, no asteroid struck the Yucatan Peninsula. No extinction of the dinosaurs took place at that time. Instead, a disease I introduced a million years later wiped out most of the large dinosaurs along with small mammals, allowing an amphibious salamander-like creature to survive and multiply. And—voila!—one hundred million years later we have the Sallies.”
The magnified image displayed three reptilian creatures at the base of a palm tree. One stood on its hind legs, four feet tall with slick, lime-green skin and a prehensile tail. The second had yellow skin and bore translucent wings, allowing it to hover a few feet off the ground. These were the ones flying over the city. The third, a grey-scaled creature, skittered on all fours and had larger, saucer-shaped eyes and a thicker tail. Patches of fungus spread thickly across their torsos.  p. 71

Then she tells him that the salamanders—the same creatures we read about in the introduction—are the ultimate problem solvers, and that their “thinknests” have created an carbon dioxide extraction device that will solve not only their climate problem but Earth’s as well. Then Milagros asks Cory what problem he thinks the salamanders should be made to solve next, and he replies “cancer” (as he has just completed a course of radiotherapy for the disease).
So far, so Microcosmic God (a Theodore Sturgeon story where evolutionary stresses are applied to fast-living and breeding creatures to provide a series of miracle inventions). The next part of the story continues along similar lines with an account of the cancer-like “Black Scythe” plague that Milagros introduces into the Salamander population. However, unlike the Sturgeon story, we get an intimate account of the dreadful pain and suffering the Salamanders experience:

The great plague descended upon the People of La Mangri first, killing innocent larvae in their developmental stages, rendering entire populations childless. Then the cell mutations spread to adults, bringing a slow and agonizing death to millions.
As the decaying corpses gave rise to more disease, my great-grandmother Und-ora devised stadium-sized pyres to mass-incinerate thousands of the dead at once.
She also led local thinknests in their frenzied attempts to determine the origin of the disease and stop its spread. When the cell mutations proved to be non-contagious, they studied possible environmental causes of the illness. But hundreds of Houses of different regions with radically different diets, customs, and lifestyles were all similarly stricken. With no natural explanation at hand, thinknests around the globe independently arrived at the same inescapable conclusion: the plague was another Divine test. The People assumed they had proven themselves worthy when they implemented the Extractors, purifying the atmosphere of the gods’ deadly gases.
But the gods were capricious.  p. 72

Then, after the Salamanders develop a cancer-curing Revivifier, Milagros causes an asteroid strike, which forces the thinknests to create an Asteroid Defence program. These events cause the Salamanders to turn away from their devotional religion and to an examination of the nature of their (unknown to them, virtual) reality.
Matters develop when Cory (under pressure from his boss to publish) interviews Milagros in bed (they have become lovers again), during which they discuss whether the Salamander’s suffering is “real”. Then, after Milagros falls asleep, Cory goes into the lab to record an “alien attack” on the creatures so he has some material to fall back on in case she doesn’t allow him to publish. When the Salamanders subsequently defeat the aliens that Cory has introduced into their world, he then programs “cosmic hands” to give their planet a shake. During this second event the salamanders see “God’s fingers” and realise that it is another divine attack.
It’s at this point that the story takes an ontological swerve away from the Microcosmic God template and becomes something else entirely (spoiler): Milagros arrives in the lab (presumably the next morning) to see Cory lying on the floor. She asks him what he has done—and then the Salamanders appear:

[Cory] blinked and the Sally leader disappeared. Blinked again and she stood nearer, locking eyes with him. A forked tongue with mods flicked out of the Sally’s mouth, pressing against his eyelids.
My God, what was happening?
The cold, wet tongue retracted and time stood still. Then the Sally leader sighed deeply. “This explains so much.” She turned to face Milagros. “Finally we meet face to face, Cruel God. I am Car-ling of House Jarella.”
“How—This isn’t possible!” Milagros said, tapping the mods on her face.
“You,” the Sally said to him. “When you clutched our world in your hands every thinknest across the globe isolated the frequency of the projection and used the planetary shieldtech to trace the signal back to its point of origin. Here.” The Sally waved her thin arms in the air, turning back to Milagros. “You turned us into the ultimate problem-solvers. And at last we’ve identified our ultimate problem: You.”  p. 80

After some more j’accuse, the Salamanders spirit Milagros away to their world, and Cory sees an image of her being abused by an angry mob as she is marched towards a huge crucifix. Then the salamander who is still in the lab with Cory says that they have much in common—because they have both suffered at the hands of a cruel creator. When Cory tells the salamander that Milagros didn’t hurt him, the creature replies he wasn’t talking about Milagros, but the true Creator, “millions of simulations up the chain,” before adding, “I aim to find her and make her pay.”
This sensational revelation flips the story into another paradigm completely (one where mankind isn’t God but subject to the capricious whims of one) as well as providing a pronounced sense of wonder.
The story ends with Cory’s cancer returning, and the salamanders living in an age of peace.
Although Rivera recently stated he hasn’t read Theodore Sturgeon’s Microcosmic God¹ (although he has read George R. R. Martin’s Sandkings), it’s interesting to compare the differences in the two works. Rivera’s story:
(a) is more contemporary—it has better prose and a modern setting, and Milagros’s aims are probably more in tune with a modern readership, i.e. altruistic rather than the monetary/political aims of the two main characters in the Sturgeon;
(b) is more empathetic—we see the struggles of the Salamanders and the cruelties visited upon them from a first person point of view, whereas the Neoterics in the Sturgeon are offstage or more generally described (and that story never addresses the moral or ethical problems of their appalling treatment);
(c) shows more agency—the Salamanders are players who transcend their reality, whereas the Neoterics are largely pawns;
(d) is more complex—the simulation chain idea makes it a Microcosmic God-plus story;
(e) is more reflective—the occasional meditations on suffering and supreme dieties, and the fact that the story moves away from the idea of “man as God” in the Sturgeon tale to one of “man as cog” (in a larger machine or sequence of realities).
Rivera’s story is an impressive piece, both in its own right, and as a riff on a well-known genre story. It really should have been a Hugo finalist.
****+ (Very Good to Excellent). 8,350 words.

1. Ray Nayler (another Asimov’s SF regular) interviewed Rivera about his story here. I think Nayler lets his preoccupation about the shortcomings of capitalism somewhat blindside him to the more obvious themes of the story, i.e. man as God, and humanity’s appalling treatment of other species. These two issues appear, to a greater or lesser extent, in the two stories already mentioned as well as another two related pieces, Crystal Nights by Greg Egan (Interzone #215, April 2008), and Sandkings by George R. R. Martin (Omni, August 1979). The theme of man as God is particularly prominent in the Egan (and it is the only one of the four pieces where the protagonist alters his behaviour towards the subject species when he realises they are suffering) whereas the Martin is almost entirely about the main character’s sadistic treatment of his alien “pets” (the piece is essentially a “let’s set an anthill on fire for fun” story but, notwithstanding this, a gripping story and a worthy multiple award winner).
