Ya that's a level of unmitigated bull** where I live there is usually several days out of the year where the temperature is -40 (doesn't matter the units at that temperature it's the same) and massive wind chill. There's not really a reasonable way to heat a houseduring the day and have it remain warm with tempratures like that without major changes to the way houses are built.
This seems like the quintessential example of some Cali tech bro nor understanding that there is anyone outside of their little bubble and assui everyone just lives like them.
