I like not having to get up and walk across my house to reset the internet because my ISPs modem is garbage and locks up under heavy load.

I like being able to schedule my plant's grow lights to get the appropriate amount of light regardless of season and being able to keep that schedule even when i'm not home

I like knowing that I left my garage door wide open as I drove away because I forgot to look back over my shoulder to see that the button in my car didn't get picked up.

I like being able to unlock the door for my neighbor to let my dogs out if I end up stranded at work longer than I had intended to when I left that morning.

I like that my garage camera turns on and takes shots of whoever is entering though the door when its opened.

I like that my system texts me if a door/window is opened after 10pm (if its me? no biggy. If its an intruder? BIG HELP)

I like that these devices are on a segregated VLAN with firewalling protecting my personal computers/NAS

There's a lot of negativity to be said about smart devices, but you can't focus solely on the negativity while ignoring the advantages.

There's also a level of risk and comfort each individual should be willing to set for themselves. I don't 100% trust my garage automation, that's why I have monitored security on my house. I'm not willing to automate devices that can harm my house (oven as your example) but I am willing to monitor their power state (is the oven on?)

This isn't all or nothing in the end.

Your dual-edged sword is a valid argument, but one can only set the level of risk and comfort iff he/she is aware of the risks in the first place. Look at how busy the Best Buy "Geek Squad" is setting up TVs' and helping new owners with use of their smart remote! :-)

“Ghastly,” continued Marvin, “it all is. Absolutely ghastly. Just don't even talk about it. Look at this door,” he said, stepping through it. The irony circuits cut into his voice modulator as he mimicked the style of the sales brochure. “All the doors in this spaceship have a cheerful and sunny disposition. It is their pleasure to open for you, and their satisfaction to close again with the knowledge of a job well done.” - Douglas Adams, The Hitchhiker's Guide to the Galaxy

People just can't get enough of Alexa and her Genuine People Personality!

The door refused to open. It said, “Five cents, please.”

He searched his pockets. No more coins; nothing. “I’ll pay you tomorrow,” he told the door. Again he tried the knob. Again it remained locked tight. “What I pay you,” he informed it, “is in the nature of a gratuity; I don’t have to pay you.”

“I think otherwise,” the door said. “Look in the purchase contract you signed when you bought this conapt.”

In his desk drawer he found the contract; since signing it he had found it necessary to refer to the document many times. Sure enough; payment to his door for opening and shutting constituted a mandatory fee. Not a tip.

“You discover I’m right,” the door said. It sounded smug.

— Ubik, Philip K Dick, 1969

I'd go further: smart devices are largely a status symbol. You're advertising to your guests that your concerns are those of convenience and luxury, to the point where you won't even use a light switch. That alone is pretty gross before you add in the implicit support for the megacorps.

That's a little too cynical.

I use smart home stuff, because: 1. I use it as security device (i have tons of zigbee sensors for motion, and contact). 2. I forget about simple things, all the time. I forget to lock my door, i forget to get my keys etc. All of this is taken care for me in case i forget. I haven't hooked up my garage door yet, but my kid (1 yo) likes to find the remote and press it mindlessly, and i really don't want to leave it open. 3. I like the convenience in general.

If you come to my house, it's definitely not something you'd say a "status symbol". It's only expensive because it's in bay area, otherwise it's a mediocre house.

I have been a programmer for as long as i remember, and these things excite me, that's another aspect.
