I just had to buy a new microwave.
The amount of 'Works with Alexa' type things I was being marketed at, absolutely insane. I have to physically go to the microwave to take things out and put things in, why in god's name would I want it on my network?
A dishwasher, washing machine, etc? Come on now.
I do think there's probably some light use case for some 'cool fun hacking' stuff...but that would be niche, and I'd never want it to go out of home network.
