I think the catch with AI and ML there is "reason" but it's just math or something that happens because.
If it is "reasonable" (trying to find a definition here) can only be determined by humans.... provided they care or understand it.
I always quote this one but I really like it:
“Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.”
― Frank Herbert, Dune
I would argue that it is clear that to some extent, Google does not care about the end results.
