Most the time, keywords, review and other aspect for the answer. So, the list is not 100% correct and some of "site-casino" is included. Need to be listed by our self as well, since the data is from internet too.
The data is from the INTERNET only. Not sure what is the algorithm behind fetching those results but definitely it could not be validated just like that. We should really have less dependency on such results or questions which are vaguely answered based on what "others" have written somewhere on a blog site or review site for that matter.
I would not hold my breath on whether people will eventually learn that artificial intelligence can be reliable to substitute an appropriate investigation on ourselves. For example, I already have a friend who is getting used to using AI to ask for questions and information to work with, instead using a browser and search for what he needs manually.
Imagine a scenario someone new to gambling ask the AI about a reputable casino and ends up using 1xbit or any other shady casino because the massive shilling on internet affects what the AI says.
