> Auto-tweening has basically displaced hand animation for most TV cartoons. That's got nothing to do with AI, it's just economics, and it's been like that for years. Everybody doing animation on the cheap wants to avoid drawing every frame. Prior to digital animation you used other techniques, like recycling frames or tracing over existing drawings (Disney used to do this all the time in their films). What digital animation really allowed to happen was 2D puppeteering, where you could rig puppets and animate them in two dimensions without having to draw the key poses or the in-betweens. Now we're at the point where the standard way to do 2D animation is via puppets, rather than any sort of hand-drawn (be it key poses or full tweening)
