The short answer is Christianity isn't a utilitarian belief system. While God loves everyone equally, he puts some of us closer together in love: family, friends, neighbors, countrymen. This incurs a greater obligation, plus we ought to love more those who are closer to us.
Sadly, a lot of Christian faiths teach dogma before the underlying reasoning or take a Bible-only approach which I find to be incredibly incomplete. In case your upbringing didn't include much theological reading, I would strongly recommend Civitas Dei and Summa Theologiae; the latter is less explicitly relevant to its definition but probably a better book overall.

I think theologians will hang on for a while saying "what AI is doing isn't really rationality". But eventually the theologians are going to face a reckoning: what AI is doing will look so much like rationality that they will be required to answer the question "what specifically differentiates the two?" and then they will be stuck. Neuroscience does not understand how our brains produce rationality nor do our AI scientists understand what algorithms their neural nets are implementing post-training. Therefore, any specific claim the theologians make runs the risk of immediately getting invalidated by some scientific discovery on either side (theologians these days are generally smart enough to avoid putting themselves in that position.)
From Aquinas' Summa Theologiae. The argument this article presents does seem very similar. Weirdly, the article itself is very dismissive of religion, while making a similar argument to the one Aquinas made 750 years ago.
