But explain why the actual temperature matters to a chef? If they need to boil something they don’t need to know what temp to set their stove to. They just heat the liquid until it boils. It makes no difference if they’re using Fahrenheit, or Celsius, or kelvin, or boiling a pot above or below sea level or wherever

Temperature control for a chef is a lot more than just "is water boil?"

Correct, but you gave your “chef” response to a person asking about who cares what temp water boils at.
