is it more than just the tech? just spitballing, but maybe it's a culture thing too?
the flash era had everybody being animators on newgrounds in junior high and/or high school making fully animated (shitty but animated) cartoons, so they'd already had years of making cartoons under their belt by the time they got to college.
it seems like youtube has changed the animation scene, so now everyone is a lot more accustomed to releasing lower effort pieces, both with sketchy slideshow "animatics" and by leaning on the crutch of pre-existing, funnier audio. (not that shitty newgrounds stuff didn't use crutches like endless vidya parodies, but at least they were usually trying to write/voice their own shit).
maybe this is fine, maybe this makes more sense for the industry they're getting into. but it seems like it might be making a much more boring, complacent, subservient generation. and those are adjectives that are surprising to associate with the concept of "cartooning."
i dunno, i was never an animation student.
