Weather/room temp wise we probably never will. I’d rather think of my environment in terms of 0 to 100 than in terms of -18 to 38. For science and engineering, Celsius is ideal, and I can convert between the two in the very rare occasion I need to because I’m not an idiot who can’t do basic math.
That’s entirely a matter of habit. There is nothing special about 0°F (random point in the cold range?) or 100°F points (random point in the hot range?), you’ve been lied to.
We don’t think -18°C to 38°C, we think -50°C to +50°C (regular Celsius weather thermometer, covers almost any temperature observed on Earth), with 0°C differentiating between snow/ice, “wintery” weather, and rain/mud, “non-wintery” one. That’s how we know whether to take umbrella (no point if it snows, hat is your best friend), what kind of shoes are the best fit - cold-resistant or highly waterproof - or which kind of jacket is gonna fit the situation. Melting point of water is actually incredibly important weather-wise and entirely ignored by Fahrenheit scale.
When it’s not winter, normal range is 0-40°C, with 20°C designating comfort temperature.
Aviation is already backwards; aviators give distance to travel in nautical miles, visibility in statute miles, altitude and runway length in feet, speed in knots, weight in pounds, volume in gallons, and temperature in celsius. My favorite is the standard adiabatic lapse rate is given as 2°C/1000 feet.
