no,
if someone learns art on digital systems they can grab a pencil and do the same on paper. maybe they'll be annoyed by lack of the undo button, maybe they'll have to learn colour mixing, and how materials interact with each other, but the core ability to make art is fully transferable between ditigal and paper
same goes for animation. btw. your statement about it doesn't make much sense, keyframes are a concept used by both digital and traditional animators. and if you meant frame interpolation then it's a brute force calculation of the most average of averages given two data-points, 90% of the time the animator has to go back and fix it, developing their animation skills that they can then take to paper and do just the same (would just take way longer)
now what will a prompt typer do without their AI?
fuck all is what they'd do. the only transferable skill from that would be idk writing image descriptions for the visually impaired
