Okay, and? Hand written papers haven't been a thing in nearly 2 decades unless it was some form of punishment. Also, teachers don't want to have to context switch between reading each paper, adjusting to each student's handwriting
You listed the one exception to the rule. Most AP tests (physics, math, econ, etc) don't have that. Even the SAT essay is gone. That one AP test the final stronghold for an obsolete medium
The ones you listed still have FRQs that require critical thinking. Econ is writing a paragraph and drawing a graph, as I recall, and Physics has a question where you have to reason out an experiment. And all of the history and english ones require long form writing.
Weird, I don't remember writing paragraphs for any of those tests. I took almost all the AP tests available, tho that was a decade ago. At most I labeled some axes and that was enough for perfect scores
