Some of the biggest channels on YouTube right now are those story time """animations""" though. They make mad bank pumping out all sorts of merchandise like board games or shitty books that no one wants and get invited to the rewinds and all the other stuff from the YT inner circle I'm sure. If Arin wanted to get back into animation, he wouldn't even have to try considering the norm now is more slideshows than animation, and just drawing your persona in 4-5 different poses and copy pasting them throughout the video.
Hell, he wouldn't have to stick to the story time format, people do all sorts of things in the feigning animation genre. He could do awful reviews, deliver more cringy social commentary on topics no one cares about, unfunny reaction videos, the possibilities are endless. Arin just doesn't want to animate/draw anymore, and any time he whines about how he wishes he could he's just lying or too lazy to even draw a smug picture of himself crossing his arms and talk about nothing for 10 minutes.
