> It doesn't need more. Labour was 8% of what it cost Unitree to make its robots in 2025, outsourced assemblers included, and most of the rest was parts

Ok, but what drives the cost of the parts? I am sure the parts manufacturers spend on labor, and the parts the part makers buy depend on labor. Labor drives all vast majority of the expense if you go all the way down the supply chain.

If we automate more and more of that labor with robots, then it drives down all the costs.

If we get truly autonomous robots that have the mobility and precision of humans, they could replace all of the labor. The 'switching' cost goes way down compared to the machines that do the work today.
