I thought of that too and looked into it. (Or rather had an AI look into it! ;-)) Fortunately, there are extreme physical constraints on how quickly manual labor could be replaced, especially anything requiring dexterous work. Mainly, supply chain constraints on rare earth elements, which are required to make these motors feasible.

By some estimates, today's global supply is like 2% (or was it 0.2%?) of the total amount required to enable such widespread deployment of robots. Until we can scale that up (or figure out how to bypass that dependency) there is a very hard constraint on how fast they can be deployed.
