I mean, I actually knows modern real-life spiritualistic objections against strong AI development.
1) As you can't create spirit by tech means, creation of strong AI is impossible. It's nothing they actually "oppose", they just scold people who tries for trying. So by no means such a spiritualist would actually against using AI - he just will refuse it's, well, being strong.
2) Trying to actually create something sapient is an intrusion into Almighty domain, and therefore it's a sin. Sin is bad. Even if you, by some divine spark, will create strong AI, it will lack spirit, therefore it will lack morallity, intristic value of human life et cetera (read - "will be a fanatic materialist"). This people will ban creation of AI, high five, but they should be religious and have specific ethic system, not just being somebody who "prioritizes deep introspection and a belief that perception begets reality". Also that's not fit examples of Jedi and Sith, who, actually, use strong AI without any moral problems.
3) It's quite possible to actually create strong AI, but we haven't moral right to create something sapient and filled with a soul just to exploit it. This kind of spiritualist actually should demand civil rights for strong AIs.
But I can't see nothing in "prioritizing deep introspection and a belief that perception begets reality" as it is, that obliging somebody to oppose AIs.
Of course, it's possible you're actually mean "Spiritualism represents a belief system that supports and prioritizes deep introspection and a belief that perception begets reality
and some other things I believe fits here, but I won't name". That's change meanings of terms as you want in the middle of discussion.
Or it's fair asking to actually say - why spiritualism bans robots and don't bans another material tools.
A Materialist society (or at least, government) simply doesn't have the right mentality to foster psionic development, and thus will never be able to observe it on a sufficient level to develop the extensive, powerful psionic technologies we see in-game.
Materialist (truly materialist) society don't "have the right mentality" or "don't have the right mentality". Drop that presuppositions and mystical crap and thoughts that world is the thing how we see it for spiritualists.
"If the sky is blue, I desire to believe that the sky is blue. If the sky is not blue, I desire to believe that the sky is not blue. Let me not become attached to beliefs I don't want." is the basis of materialistic science - because they ARE NOT BELIEVE THEIR PERCEPTION BEGETS REALITY. Yeah, real-life scientists are not always ideal this way. But that's not because they're materialists, quite opposing way. It's because they believe that world is the thing they want it to be.
