Arguably voice assistants are still ahead of their time. My Alexa is handy for a few things like setting an alarm--though I still want to set a backup for something like an early morning airport pickup.

But for an interaction in the car to see some available podcasts and play an episode? It's just not "smart" enough. And you go through a few rounds of frustration trying to get an assistant to do something and you just stop trying.

There are specific use cases. E.g. my dentist uses one as a timer especially when he's gloved up. But generally they're pretty optional.
