Ok so, having watched a couple more videos in Lancer's lore series, i wanna point out that NHP's are basically seed AI's that have literal infinite capacity for growth and quite literally think themselves beyond human comprehension and causality itself(among other stuff) if not shackled to restrained growth and cycled every 5-10 years(basically memory wiping). Im pretty sure that makes them the most powerful AI's on this list overall, trouble is given how they're made...well they're not really AI's in the way we know them, basically they're fragments(or something similar i guess) made by the paracausal entity/God known as MONIST-1 that literally showed up in existence after being simulated by the Five Voices on Mars(really powerful AI's that can simulate the universe so perfectly they can predict the future, which Union very much used to its incredible benefit with Galactic Simulation,do we get that by the way? planning shit out at galactic level would be great, if a little OP) at Deimos(which is why its named the Deimos Event), literally took the asteroid and crew with it out of existence, then showed back up later and caused a system wide robotic uprising in Sol(seemingly out the ass like with everything else it does,they're also implied to be psychic due to another similar entity Metat-Aun) and bought Union to its knees, which after some more shit happened with the First Contact Accords(which forbade humanity from trying to learn how MONIST works and researching post-human tech) NHP's started to pop up(and only show up when MONIST appears and disapears seemingly at random places) which makes our supply of NHP's limited since im guessing MONIST isn't gonna show up in 40k,i still think NHP's are gonna be a great boon. Also although limited in supply, Union's paracausal tech seems like it will be really good given what the afformentioned top dog entities are capable of.
Also, SPACE communism. Cmon guys,we need SOME space commies on our team since the Feds aren't getting picked, id be great to have some in 40k for some much needed revival of hope(no the Tau aren't commies,they're fascist oligarchs posing as commies)
