Detailed explanation
The grammar point ～ときている is used to emphasize that some circumstance is particularly notable—often negatively. It implies, “Given that things are so ~, it’s no wonder that...” or “Because the situation is (too) ~, such-and-such follows.” It is relatively informal and more common in spoken language.
