I beg to differ. Tactical use of a scientific or graphing calculator can absolutely replace large parts of the thinking process. If you're testing for the ability to solve differential equations, a powerful enough calculator can trivialize it, so they aren't allowed in calculus exams. A 10-digit calculator cannot trivialize calculus, so they are allowed. That's the distinction. LLMs operate at the maximum level of "helpfulness" and there's no good way to dial them back.
