That really sounds like the kind of people who will complain in university about being forced to study calculus.
Natural consequence: Then they never grasped the concept of computational complexity.
O(n) Vs O(n²)? They have n, what's the difference? Python is fast enough. The only thing that matters is shipping features fast! Features! Our competitor will have this next week, we need to write code fast, everything else is a matter of adding more compute, which we will pay with revenue!
computational complexity was never part of calculus. Calculus is the math of continuous change.
As a side note; There is plenty of useful math that many people need (or would benefit from) in the real world. Much math curricula is arguably poorly aligned to needs, as it emerged from various historical flukes of design-by-committee. Popular math curricula is not perfect by any means. I recommend looking at high school or college textbooks and considering whether it is well prioritized.
