The magic of the Genesis device is quite ridiculous either way. Its up there with the Spore Drive in terms of ridiculous bullshit we've seen in Star Trek. I'd be willing to even include the Transphasic Torpedos, the Chroniton Torpedoes and, oh yeah, an entire fucking Dyson Sphere in the list of incredibly OP shit that Starfleet seemingly just forgot about. Also the remains of the Planet Killer which somehow remained intact after they blew it up. And that shielding system that lets you fly into a sun. And also the fact that you can just timetravel by swinging around a random star so long as you break away at the right time.
Star Trek is no stranger to OP tech, the Spore Drive is just the most egregious one because they based a whole show off of it.
Oh quite right. I'm not saying the Genesis device is flawless and all. Like you said, Trek even has a bit of a history with silly, OP tech. Heck SFDebris has an extended rant on how insane the minefield in front of the wormhole is logically speaking, but I notice nobody's brought it up.
All I'm arguing is that the Genesis device at least follows STORY logic.
To steal an example from a friend: Think about fairy tales. A common trope in them is of the mysterious old man who (for an example) complains about always being hungry. The hero will need to complete a task (like eating all the bread of a vast storehouse) so he recruits the old man who then proceeds to do it. From a pure logic stand point, this is nonsense as the mass of the food, greatly exceeds the old man's total mass. But it fits
in story because they establish certain rules - like the guy showing signs of not being normal, complaining about being hungry, etc.
The genesis device at least fits in
story logic - like DS9's minefield. The spore drive? Can't even manage that much.
Or to put another way. If the pure logic is the equivalent of "2+2=4" the the genesis device is the equivalent of "2+2=9,001" while the spore drive is the equivalent of "2+2=green." Both are wrong, but one is at least a number and closer to the right answer than the other.
