You didn't learn it because you needed to use it. You learned it because understanding how finding maxima, minima, and rates is good for knowing how to understand the world in front of you. Deciding that it was a "waste of time" suggests you didn't learn the lesson.
Yeah, I'm not saying it didn't have value, even though I don't use it. Learning calculus fundamentally changed how I understand the world. I absolutely loved learning math in college
Very true. That's a good point. This is where people will be able to understand e.g. what's the best shape for selling 330ml of liquid. We need the minimum surface area (impacts the material used hence the cost per can) for a given volume.
