I agree with Mr-914
I’ve read that the most intelligent computers in the world are perhaps as smart as a cat, in capacity to learn about the world and respond to changes. Whats available to consumers is really just a collection of millions of “if-then” statements with some fancy statistics (not to diminish that achievement). Smart Homes just aren’t smart enough to be all that useful (see Nest’s problems)
based on my corner of trying to launch consumer electronics, I think there’s also a trust of technology issue in addition to the lack of real utility preventing adoption.
