The node capturing the voice command could be the thermostat. From my understanding they are targeting very small devices.
So that could be a master home automation node, but why not also a single purpose device? I can think of more bad examples than I can good ones, but maybe I am doing some soldering and I need my soldering iron turned up a bit; my hands are full, so doing that by voice would be useful enough. Something I would never link up to a big AI model or home automation network, but could be useful to control by voice.
If it's something that can be burnt directly into a chip and shipped with the products for cheap, maybe that's a more pragmatic way to get AI into small devices (see taalas for a much bigger model doing that, althoug not yet cheap).
Oh I agree that's not unreasonable. I wonder about the harnessing heft required to make it feasible though. If I say I'd like it a bit warmer, a tool can deterministically bump a few degrees while an LLM might bump it 10C. So do we limit the tool's range?
