I just find it extraordinary that the biggest tech company in the world can do cutting edge real time AI for millions of people, run Youtube and of course all the other google services with having literally the smartest people in the world and unlimited resources on board, but still can't keep real time track of the user's current billing and their spending limits, it's all best effort still. Somehow it doesn't add up. (Pun not intended, but I'm happy to have it)

If spending caps made them more money they'd find a way;)
