As long as it is used as a tool that has human refinement as part of the process it would be comparable to CGI replacing background matte paintings and motion capture replacing manual manipulation of CGI to make movement. Gollum worked because of the blend of technologies that were replacing existing practices, but as a new approach and not a cost cutting measure.
The problem is entirely about using the output directly as a replacement for humans to cut costs, not having another tool that can be used as part of a process. This is coming from someone who absolutely hates LLM and genAI slop, which is taking the horrible approach.
