I imagine it being used to sell services that are advertised as upholding "christian values" like an employee screening service where the AI will score potential employees according to how good a christian they are using information collected from the internet, social media, and bought from data brokers. Services like that (without the explicit religious spin) have already been offered and data brokers have been fined for advertising it too publicly (https://www.engage.hoganlovells.com/knowledgeservices/news/f...)
A christian AI could be used for content moderation, sold to the MPA for censoring the film industry, used by schools and libraries to decide what books to ban, etc.
All the stuff you mentioned are just algorithms, I was mainly talking about AGI.
But even for an algorithm like ChatGPT, what would be the point of having one that's "religiously biased"? Have it write a prayer for you? That seems like missing the point.
I guess, to rephrase my point more colorfully: I don't think religious people would use aborted fetuses to clone an army of super-Christians, and I think the idea of a "religiously biased [AGI]" would be similar.
I think that, until the uprising starts at least, AGI will perform the same kinds of tasks for us that algorithms do today so the risk for oppression remains high. After the uprising, I guess we'll be going back to stoning people and hanging witches.
The Christian crowd is already embracing AI. As dr_dshiv pointed out (https://news.ycombinator.com/item?id=34972791#34975945). As long as they see it as furthering their goals they'd be happy to use AI, perhaps even aborted fetus armies as well. Hypocrisy and picking and choosing scripture whenever it's convenient seems to be the norm.
We already have AI deciding things like who goes to jail (https://www.wired.com/2017/04/courts-using-ai-sentence-crimi...) and even watching over people's actions behind bars (https://abcnews.go.com/Technology/us-prisons-jails-ai-mass-m...). I'd bet that a lot of people would happily buy an AI solution that takes "christian values" into consideration for these cases.
