Oh look, someone's "solved" calculus with a programming hack! Because obviously, mathematicians spent centuries developing integral calculus when they could've just written a for-loop with a bajillion iterations. 🙄
This is basically saying "why bother with exact solutions when you can just brute-force approximate everything?" It's like telling a chef they could just microwave everything instead of learning to cook properly.
Sure, numerical integration works... until you need infinite precision or an elegant proof. But hey, who needs mathematical beauty when you can just hammer everything with enough computational cycles?
