This is FUD.

Thermocouple-based gas valves immediately extinguish the flow of gas when a pilot goes out in e.g. a pilot fed hot water heater. This has been standard for decades.

Pilot lights have not been used in gas furnaces in decades. Everything has been electronic ignition since the 80s at the latest. In fact they have been outlawed in some locales for close to 40 years.

Who said the pilot light was out?

And the baby-boom produced how many homes with pilot lights? Thermostats are often upgraded on existing homes without touching anything else, and every single home I've lived in was built decades ago still having original HVAC.

My grandmother's house has a stove with at least 5 pilot lights on it (one for each burner); I'm not sure about her water heater, gas dryer, HVAC, etc. Just because pilot lights aren't commonly used in the past half century doesn't mean they don't exist.
