Meh, I work in IT and I have some of those things. Also robot vacuums. If it truly saves effort I buy it. A lot of the smart tech is more trouble then it's worth.
I am IT, and a bit of a hardware/software freak... and I have none of it, beyond talking to Bixby on my phone, and that is mainly because it is easier than hauling out my glasses all the time.
I have no need for it otherwise, and don't really find any of it to be useful... Starting with heat. Funny, but AI can't light a fire, nor throw the wood in. And right on down the line, the same thing applies. Roombas make me giggle. Heck, just in dog hair I would have to empty that thing daily, not to mention the chunks of dried mud (I am being nice here) that fall off a vibram sole.
The only other thing that seems vaguely handy is being able to tell my phone to turn on the porch light when I come home. But then, the phone has a flashlight, so...
