...because the whole point of voice assistants is to keep you from using search and since Amazon has always sucked donkey scrotum at search, they're going to suck donkey scrotum at anything designed to replace search?
My car has an Alpine car stereo with Android Auto. Its Bluetooth name is "hot lip fungus." My previous phone believed it was in Australia because I find the Australian google voice to be less dourly judgmental of my failures. Hot Lip Fungus reads my texts to me and then asks "do you want to reply?" and then gets lost between T-Mobile and the cloud and its utter inability to do anything on the device. Last time it repeated the text and then said "do you want to reply?" and when I shouted YES!!!!!! at my dashboard like a crazy person, as you must do when interacting with Hot Lip Fungus, it said "...oh" and went back to playing Test Department. Frustrating, yes. But at this point, bordering on dadaist.
In my experience, voice assistants have the same awful discoverability problem that Command Line Interfaces had. I simply don't know what the available commands are. Until they can helpfully respond to everything you could ever say to them, it will always remain a waste of time talking to one of these dumb things.
