If you wander off of that knowledge sphere, and you are not sufficiently knowledgeable yourself about the topic, it can tell you some really stupid stuff.

Nonetheless, I do use it quite regularly in everyday life, as it is basically the best reverse dictionary (that works for any language) there is. For work (programming), I didn’t find a better use case than sometimes passing it a list of stuff, giving it an example on the first element on what I want, and using it to generate it for the rest of the elements.

But that is <1% of what I do each day.
