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?
