I never found voice assistants useful, it’s almost always easier to pull your phone out of your pocket and press the relevant buttons than having to explain what you want 3 times to Alexa.
We had an Echo dot for a few weeks and sold it on, ‘tech for the sake of tech’ is the phrase of choice for me.
Im no technophobe either, I most certainly do tech but it needs to have a clear purpose.
I’ve got a full Home Assistant set up at home, running in a VM on NAS. It does useful things like automates the charging of my home battery when I get cheap electricity and turns on my outside lights when my cameras detect a person on my property.
Where I don’t see the benefit is being able to shout at a box in the corner to turn the light on when I would have walked passed the light switch which I could have just used in 1/4 of the time it took me to shout at a box in the corner.
As for paying subscriptions for cloud based cameras, that’s a hard no.
