I have an Amazon echo that is a glorified weather reporter and cooking assistant. It’s pretty useful for setting timers and for calculating conversions for measurements. I also use it as a white noise machine for bed time.
I do get the random interruptions where it some how responds to some random conversation I am having and I promptly cuss it out. It’s probably foolish for my privacy, but I don’t actively plan crimes in front of it, but who knows how it might bite me in the ass in the future.
