No thanks. I want my stove to last 10+ years. Replacing a single knob is a lot simpler to repair, and less likely to fail than the microphone, speaker, logicboard etc. in a voice stove.
FWIW my GE electric stove/oven was installed when my house was built in 1967 (52 years ago). Everything works perfectly except for one front burner, which went bad about 2005. Oven is perfectly calibrated. I bought the house (and stove) in 1983 and have never required a service visit. When I mentioned to an appliance tech who was installing a new Maytag washer/dryer that I was thinking of getting a more modern stove, he said, "Don't."
None of those parts could be expected to break. This wouldn't be IoT. Just a static dumb voice control system on an SoC.
But I'm with ya. My stove is turning 15 this year. Looking forward to it being able to drive next year. Maybe I can even expect some bouncing baby grandstoveren a few years after that (but hopefully not too soon, there's so much world out there for a young adult stove to see).
