(...) the term technical is a red flag for me, as it is many times used not for the routine business of implementing ideas but for the parts, ideas and all, which are just hard to understand and many times contain the main novelties.

Why don’t animals have guns?
Or why didn’t evolution evolve the Hydralisk?
Evolution has found (sometimes multiple times) the camera, general intelligence, nanotech, electronavigation, aerial endurance better than any drone, robots more flexible than any human-made drone, highly efficient photosynthesis, etc.
First of all let’s answer another question: why didn’t evolution evolve the wheel like the alien wheeled elephants in His Dark Materials?
Is it biologically impossible to evolve?
Well, technically, the flagella of various bacteria is a proper wheel.
No the likely answer is that wheels are great when you have roads and suck when you don’t. Roads are build by ants to some degree but on the whole probably don’t make sense for an animal-intelligence species.
Aren’t there animals that use projectiles?
Hold up. Is it actually true that there is not a single animal with a gun, harpoon or other projectile weapon?
Porcupines have quils, some snakes spit venom, a type of fish spits water as a projectile to kick insects of leaves than eats insects. Bombadier beetles can produce an explosive chemical mixture. Skunks use some other chemicals. Some snails shoot harpoons from very close range. There is a crustacean that can snap its claw so quickly it creates a shockwave stunning fish. Octopi use ink. Goliath birdeater spider shoot hair. Electric eels shoot electricity etc.
Maybe there isn’t an incentive gradient? The problem with this argument is that the same argument can be made for lots and lots of abilities that animals have developed, often multiple times. Flight, camera, a nervous system.
But flight has an intermediate form: glider monkeys, flying squirrels, flying fish.
Except, I think there are lots of intermediate forms for guns & harpoons too:
There are animals with quills. It’s only a small number of steps from having quils that you release when attack to actively shooting and aiming these quils. Why didn’t Evolution evolve Hydralisks? For many other examples—see the list above.
In a Galaxy far far away
I think it is plausible that the reason animals don’t have guns is simply an accident. Somewhere in the vast expanses of space circling a dim sun-like star the water-bearing planet Hiram Maxim is teeming with life. Nothing like an intelligent species has yet evolved yet it’s many lifeforms sport a wide variety of highly effective projectile weapons. Indeed, the majority of larger lifeforms have some form of projective weapon as a result of the evolutionary arms race. The savannahs sport gazelle-like herbivores evading sniper-gun equppied predators.
Some many parsecs away is the planet Big Bertha, a world is embroilled in permanent biological trench warfare. More than 95% percent of the biomass of animals larger than a mouse is taken up by members of just 4 geni of eusocial gun-equipped species or their domesticastes. Yet the individual intelligence of members of these species doesn’t exceed that of a cat.
The largest of the four geni builds massive dams like beavers, practices husbandry of various domesticated species, agriculture and engages in massive warfare against rival colonies using projectile harpoons that grow from their limbs. Yet all of this is biological, not technological: the behaviours and abilites are evolved rather than learned. There is not a single species whose intelligence rivals that of a Great ape, either individually or collectively.
