My favorite use is to give me PhD level tours of art museums and historic sites. It seems to know everything about every single artwork, the lives of the artists, and the economic and cultural context. It's willing to go at my pace and field as many or as few questions as I want.

Frequently use it to come up with recipes when cooking, repair electrical equipment, or seek medical advice and results interpretation for my family.

It's pretty hard to imagine life without it at this point. I know it's possible, but like the internet, I would feel crippled by the lack of information and things that I can no longer easily do
