I hear China is doing a lot of this already to stave off their upcoming demographic collapse. I haven't seen raw details or videos though other than demonstration stuff (anyone have anything to share?)
Factories have been automating for decades. Last factory tour I took they said in 1950 this plant had over 2000 employees working, now (2019) about 200. Then he pointed to the laser cutter which alone replaced 150 workers with just 2. This factory is not considered very automated by modern standards either.
