Use of AI robs you of the opportunity to learn/practice/hone your skills in a certain area. why would someone use ai for any reason other than to get out of having to learn something?
This is not really a good argument against AI. Almost everything ever invented was invented to avoid doing something else that would take more time.
Why would anyone use animation software other than to avoid learning to draw your frames in sequence?
Why would anyone use a loom other than to avoid having to learn how to weave?
Why would anyone read a book other than to avoid learning by experience and experimentation?
