your post is a little confusing to me anon. are you sperging literally because of python? or is it because of 3D CGI computer animation moving into the realm of hand-drawn anime production?
For the first point, Blender is written in C and C++, with just a smidge of Python for UI management mostly. For the second point, Glorious Nippon has been doing that for a long time now, much earlier than it became common in the West to do so.
