hahaha. come on Joe, you're only 62. You're not supposed to be that out of the loop yet.
Siri is Apple's little voice assistant that's built into all iPhones, and has been for many years now. I just tell my phone something like, "search for images of asparagus", then show my phone to Leo / clerk, wait for something to get put into my hands, and feel it out to see if that's what I want or not.
I could understand if you don't know who Alexa is yet, but you should know who Siri is by now.
