I am using it almost daily. It's better than Wikipedia.

Its kind of like rubber ducking with a fairly smart duck. Plus the variety of topic one can ask it is infinite (as opposed to Wikipedia)

It also responds in a very humanly way (tell it you are feeling anxiety for example)

In the last 10 or maybe even 20 years it's one of the few new tech that has had me stunned.

Sometimes I make it create poems too, very simple ones on things very contextual.
