Now sure what sucks on Celsius, water freezing and boiling have been some of the most important scientific and just plain existence facts of mankind since we evolved. We humans have 10 fingers so its split by decimal system.
Since we humans operate 99% of our existence in a narrow band between 0 and 100 degrees celzius, I'd say its more important than starting from absolute 0 and dealing constantly with big offsets.
0 or 100 or -100 or 10 Fahrenheit is what? From Gemini: "0°F was the lowest temperature achievable with a mixture of ice, water, and salt (brine), while 96°F was set as the approximate temperature of the human body (blood heat), chosen because 96 is easily divisible by many numbers, allowing for finer divisions" - rather insignificant things.
In Celsius, my daily life uses values from ~ -20 to +30 for the weather, but from ~0 - 90F. For cooking both are equally arbitrary, as the only place I set or read a temperature when cooking is candymaking, setting the oven, or cooking large amounts of meat.
