Chroma-key tool that uses AI?

Hey! To preface this, I am VERY against the use of generative AI and LLMs. I had stumbled across this YouTube short about a dude who uses neural networks (basically AI) to chroma-key videos so perfectly to the point that it even recognizes translucent materials.

It uses original models and images for the database and doesn't steal from any other source. I was very ethically on the fence about it being AI in the first place, but I'm curious what more critical people would think on this matter.
