As far as I know, AI already helps operators track suspicious betting patterns, spot bonus hunters, not to mention the very popular use of AI in customer service, to analyze and improve interactions with users.
But AI is about so many things and is, of course, only a generic name for a multitude of tools and services. AI bots are an issue for casinos, but I also believe they're an issue for gamblers. When you just give funds to a bot, you give away your control, your experience. Doesn't it take away all the fun from gambling?
You are right, I was reading a comment here when some users still mentioned that AI have been used by casinos and bookies for decades but with a different name. You have now explained all the import stuffs that casino used to achieve with AI which is really of more advantage to them but gamblers are never going to get such great achievement with AI because what gamblers wants more is to always be winners on the long run and it's never possible that AI can help them to achieve it.
