So I have some problems with the concept of The Borg.
First and foremost - who the fuck flies around in a giant rubix cube? Does each cube come from a bigger cube, like tiny cubes pooping out of a greater, larger cube?
Why shouldnt they fly around in cubes? Areodynamics are irrelevant in space travel. And why shoud they "poop" out of other cubes? i dont get the question. In fact, if we accept the theoretical concept of warp drive, all space vessels would probably look like this or similar because its most "space per surface"... a pretty klingon "Bird of prey" is just pleasant for the eye but its wings have no purpose (maybe if entering an atmosphere)
Second, why are those being assimilated only humanoids? Are you telling me that the Borg are sophisticated enough to develop large interstellar cubes but they can't assimilate anything other that is generally ape-like? Why not giant spiders or sharks with lasers on their heads?
Well, hence most humanoid races have similarities, its likely that a cyborg culture and its Nanotechnology only works for them. And they tried, It did not work for species 8472 e g.
Third, Borg seem to make babies in microwaves. If you can microwave your own babies, why do you need to assimilate other cultures at all?
Because these Babies are not grown with "distinctive features and knowledge" to add to the collective. Many actual species on earth have several ways to reproduce, sexually and asexually,whatever the situation demands,
Fourth, Picard was what Locutus of Borg or something like that? And people just forget that he was captured by a deadly enemy and was their leader and then he becomes an admiral or something and no one questions it?
Well, it was questioned and Picard faced a lot of reservation by those who suffered under the Borg, Sisko e.g.
Finally, Picard had the chance to destroy the Borg forever by implanting a virus into their netscape or hive mind or whatever and chose not to do so because ... life? Bad call bro.
Wasnt that janeway? Yes that was a deliberate point of philosophical discussion where the writers intended that probably most viewers held the view, that it was legitimate to implementt the virus in self defense. Maybe it should highlight Starfleets high ethics... later the Federation was less focused on their principles and more on survival, see the virus Section 31 introduced into the founders
