Voice assistants have been great in my experience for smartphone stuff. Dunno about ai bullshit

Few examples:

Come home in the evening with a bunch of groceries: “turn on the lights” is handy. I don’t see great and yet I’m irresponsible and will walk into a dark house with way too many bags in my hands

Cooking: again, hands busy. Change lighting, set timers, play music, etc

General laziness: sitting on the couch and decide to watch a movie, set a scene for optimal lighting. Granted this one is easily handled by using phone or just standing up, but voice is easier

Solid mic choice and placement avoids the repeat myself issue, for the most part. Can be an issue mainly during cooking tasks where there can be a lot of environmental noise and loud music playing. But worth the occasional snag, imo
