I chose a toaster specifically because it's about the simplest electrical device out there, and thus pushes the thesis to the extreme. But smart toasters are pretty common: https://revcook.com/products/r180-connect-plus-smart-toaster...

And as other commenter pointed out, a smart toaster with ads or data collection can be subsidized and thus be more profitable. (Oh what a world we're headed for!)

In any case, I think the LLM-everywhere thesis holds even strong for even moderate-complexity devices like power plugs, microwaves, and mobile phones.
