You sound like an 8th grader asking the teacher when will we ever use this in real life type question. Fractions aren't that bad when like anything in life you are practiced in using them. Let's see what's faster in a kitchen, scooping something by measuring cup or trying to get a specific weight by 0.1g precision? I'm home after working all day trying to feed myself and mine. I'm not trying to win a start for my restaurant by the Michelin man.

These incessant arguments of "why is someone doing something different than what I'm used to so stupid" are funny if not tiring. Why not ask why are there so many different spoken languages in the world instead of just speaking like me? We could go into if Rust is better than Go, or why Romulans are better than Klingons. The problem is that nobody wants to understand the differences and just want to rag on the person opposing their views. Yawn
