The AI is one thing. But it's also about conversational assistants generally being largely superfluous for a lot of people including myself. I use the Alexa in my bedroom as an alarm clock but I'll have a backup for anything early and critical. I started using the Alexa in my kitchen as a timer mostly because I find the timer on my new range a bit clunky to operate. I'd actually rather use something with a visible countdown.

Siri is occasionally useful in the car if I'm by myself but mostly in the better than nothing sense.

I think it's fair to say that a technology Amazon was, at one point, going to fill a building in downtown Boston to further develop has been extremely underwhelming.
