alt Hacker NewsAdvanced calculators are in an unusual space with external constraints on it. Some of the features or differentiation they add serves the constraint of "if you don't, we won't let students use it in the classroom".
When a calculator is used in a classroom, there's a concern about people using the calculator to replace the skill that's being taught. So, for instance, there's space for a calculator with no CAS, for a class that's trying to teach you to do algebra. That is in some ways easier than "don't use this function of the calculator".

My linear algebra class used F_2 as our field probably half the time that it was specified. Realistically almost any course probably doesn't need calculators at all (or they could at least be kept for homework). If you're not teaching arithmetic, you keep the arithmetic simple. If you're not teaching algebra, you keep the algebra simple. etc.
It is not really classroom. It is more so setting testing standard that matches the standardised testing that schooling aims for. This ofc then extends to testing in classroom tests as that is best way to prepare students.
Not that any of this matter anymore as it can be entirely replaced with LLMs in near future.
Yeah there's not really a purpose for advanced calculators anymore (apart from the niche market of people who just enjoy using them). Calculators are basically only a thing now to make it harder to cheat on exams. If you don't have that constraint, you might as well use Wolfram or Matlab or whatever.
