Maybe it's because I am used to talking to toddlers. Or maybe it's because I was such a science fiction nut growing up and am used to the idea of talking to AI, but I usually can get the information I need from Siri and find Siri very useful.
I ask very specific questions and using very stilted speech to break down a complex question into simple tasks for Siri. Sometimes I do a two step process asking one question and building on the first answer to refine the second question to get the answer I seek. I did this yesterday with math.
My daughter has a ton of summer math homework to do and my fraction skills were very rusty, which made checking the homework challenging for me. Using Siri, I was able to get her to calculate the fraction problem, which gave me the answer as a decimal and then I asked her to convert it to a fraction form. Thanks to Siri, I polished the rust off my brain and was able to calculate the rest and finish checking the work on my own. I was so grateful to Siri for saving me the time of looking for my old math books or wandering around the Internet.
Siri has access to enormous amounts of information but getting to it is very much like speaking to a small child. Sometimes children know a great deal but you have to know the right way to ask them if you want the answers.
