At some point specs don’t matter. I don’t wonder about the processor in my thermostat either. I don’t know how many horsepower my XC90 has. I don’t know the rated power of my chainsaw.

All I care about is: do they work, are they ‘safe’, are they comfortable, etc.

A thermostat’s capabilities and what’s expected of it wont change even if the tech gets better though, and that’s the key difference.
