So it is designed to work in a totally different way, within the AI. AI normally goes for Domination, Diplomatic or Space victories. I have not lost a match to an AI winning on Culture. Given that the new Cultural Victory is a new way of winning, I suspect that we are looking an AI taking that route. So perhaps it is more likely a route for Venice to take.
The one time I lost on Culture was to Polynesia who snuck up on me with a whole lot of Moai...
