I'm done with voice assistants. They don't help me at all. I've disabled Siri on all of my Macs because I never use it anymore. Feel free to disagree to this post to your heart's desire.
Well, yes, I agree it's utterly useless on a laptop. I agree with that.
However, in a smart home environment, it's pretty handy. My system allows me to turn lights on and off, set scenes, set the alarm (you can't turn it off with voice....obviously).
My son uses his HomePod Mini all the time to blare out Deadmau5 and whatever music he wants. (Alexa never understood him, and Siri just works with him). I've also set it up so that if he gets scared with a nightmare, instead of screaming, he can just say, "Hey Siri! Get mummy and daddy!" and that will turn up the lights a little and send us an announcement in our room.
He's only used it once, but it's given him loads of confidence in that he's safe which little kids need. Plus he now just uses it to turn the lights up slightly.
In the car, I use it to manage my music, but also to make calls, message using voice messages and accurately find destinations.
I understand it doesn't work on a laptop, but even I can't see any reason to have it on my MacBook Pro M1 and also have it disabled.
ETA: The temp / humidity sensor is annoying, as I've spent a small fortune installing Netatmo sensors in all our rooms.
