I'd like to have some good old organic technology! Like, umm... Well, I guess I might as well bring out my own ideas I will never use anyway
Either because they are silly or the idea they were created for were silly. Sorry for bad grammar, I'm writing bit in hurry so sorry if my ideas sound extra dumb xP
Bio drones: Genetic chimera(check from wikipedia, "a single organism composed of genetically distinct cells". Which can include combinations of different animals). Basically they are plants that grow flesh instead of plant matter(or rather like... If apple trees grew hands instead of apples? Hard to describe, maybe more like plant that appears to have "muscles" and joints and other animal like traits, but composed of plant matter instead of flesh...)), but still photosynthesize. They don't need roots though since they can consume other organic beings for nutrients. Since they are more plants than animals, they are easy to grow in masse since they can be farmed in plantations. Also, as result they are as brain dead as plants, but they still have central nervous system, so to control them you just need to jam computer in their core/head/nervous system. So basically army of animal like plant creatures that can't rebel against their creators since they aren't sentient or sapient. Might be bit dumb though since they follow the orders given by the computer programming.
Of course, you could have other chimeras or genetically engineered creatures and troops. From anything to giving mosquito like alien insect a poison equal to black mamba's poison to having all soldiers modified to have good career in muscle modeling after they retire from war ;P
Also, for non combat uses... Well, if you can somehow create a plant that grows flesh instead of fruits or whatever, assuming its edible and doesn't taste like tofu... Vegetarian society with taste for meat? xD
Also, bugs are kinda like organic robots in composition anyway, so they might be really good basis for creating genetically engineered troops, whether plant or fungus based or whatever. Either way, having organic robots instead of actual robots has some nice benefits considering some limitations of mechanical things...
Organic computers: Well, as we all know, brain are potentially more efficient than most computers. So create a genetically engineered brain computer, and you'll have really awesome super computer that may or may not turn into sentient and murderous. Would make controlling all of those biodrones easier, eh? The "Big brain in jar" computer doesn't need to really resemble any brain from any of species, after all brain was created with genetic engineering to be really powerful computer. So even if it turns sentient, it doesn't exactly need to have one "ego", it could be anything from multiple different personalities in single brain(to help multitasking) to one god like AI(that is capable of running all routines by itself).
Cybernetics combined with genetic engineering!: Well, I already touched on this with idea of "Jam computer into plant monsters to control" them idea, but it can really be expanded well. Like, maybe having nanobots that function like fungus, or genetically engineered fungus that works like nanobots. Would be creepy for enemies to have fungal infection grow out of their heads and turn their troops against them. Really, tons of potential when you go crazy both with genetic engineering, chimeras and cybernetics.
Maybe I'll write more later, fix my grammar, make better ideas, anyway, yeah, having organic technology(and combinations with other form of "Horrific" sciences) would be cool
