that would be an interesting idea... using one of the rudimentary machine learning AIs we have today to determine a user's age/maturity. How correct would such machine be? If it collects data based on posts and other openly available data?

i.e. one that looks at things like language, interests, etc. Rather than merely taking it on the submitted birthday date/year things from various sites.

What do you think of such idea?

Nah. Maturity, maybe if the AI was developed enough (it isn't at the moment) but actual age, nope. In fact, given how complicated the concept of maturity can be, even that is not necessarily likely to be a good measure.

AI is simply not intelligent enough - that I'm aware of - to make an accurate prediction beyond obvious ones that could be done manually.

I'd imagine AI would find such a wide spectrum of variables that it is bound to simply make broad sweeping predictions with little basis in reality. But then, who knows how far Ai will eventually be able to go.
