I have tested the AI and it is good at executing some sets of tasks. Besides, if you want to do something you haven't done before that involve computational activities it will provide some tip but being the end of the human race or making man lazy is what I don't know cause it's hard to predict the future and one thing I'm sure about is that the Fed's are working on some regulation that will prevent AI from ruining human race.
Having said that, AI affecting casino or gambling site activities is still a speculation by people because I haven't seen an AI that was developed to defeat the casino.
At the current stage of the AI development, it is far from ruining the Gambling industry business. AI are still full of flaw and error, it can be proven by how chatbot often messed up answers and inquiries.
The error you mentioned was due to machine learning, leveraging natural language processing (NLP), and natural language generation (NLG) used in creating the AI chatbot. However, I consider AI to be a plagiarism machine because it generates all its responses from online content.
People rank high the potential and capacity of AI due to the hype made by the influencers marketer about it.
