To me, Fahrenheit is a lot like inches and feet for carpentry. As in it's fine for things like describing the weather and setting my house's thermostat. It mostly falls apart for must other things, though it's still okay for cooking and baking. From a scientific perspective, any temperature scale that isn't zero at absolute zero is nonsense, so it's pretty much Kelvin or bust.

In traditional carpentry inches and feet make sense because of the high divisibility. We don't get as much benefit from that now though.

We still use hex with computers because that's what they're made using (rather binary, but hex is just a natural group of binary digits). The usage of binary is ultimately more grounded in the objective than the usage of base 10 in the SI system. Nature dictates the relationships between the units, but we pick the quantities so it works out to a nice base 10 set of ratios.
Base 2 naturally arises when dealing with information theory that underpins a lot of digital computing.

Say what you will about the imperial system, but you can pry binary, octal, and hex from my cold dead hands.

Arguing with the imperial system is like arguing with my mother. She knows her ways and methods are insane, but she will try to explain why she needs each of those eight furlongs. Either ADHD will steal her ability to finish the explanation or the audience will perish from exhaustion. And she still will be the smartest person in the room.

You don't have to use it though. Reject it.
