This falls into the same category as the other efforts to replace human crafts with AI: Too much uncanny valley.

Generated text looks like the person crafting it is having a constant stream of micro-strokes while writing in their third language.

Deep Fakes have a proportion problem. Not to mention little things like skin tone and lighting.

Images look like one of those “one person draws one part, and hands it off blind to someone else” activities.

And animation looks like the characters on screen are also having micro-strokes.

“It will get better,” but will it? Or will we just continue to live in the valley with a ceiling of “it’s good enough”? Getting better will be a huge cost, after all.
