Humanoid robots are notable worse than humans in many aspects that impact productivity. If a humanoid robot is ultimately 33% as productive as a worker in a developing country who gets a wage of $10k USD annually and works 8 hours per day every day, then then robot has to cost less than $10k annually all in to be a good replacement. Assuming a 5 year useful lifespan and $2k in maintenance per year, results in the robot needing to cost ~$40k before it can replace a human's productivity. And that is inclusive of training and setup, and I doubt we'll have robots that are capable of learning as quickly as average humans without dedicated specialists training them... which raises the cost.

In general, you can get a dedicated machine for most human tasks that is easily 10-1000x productivity if you have a few million in capital. There are tasks on the margin where human flexibility and dexterity that having a human operate a $10k sewing machine is going to be very very hard to replace.
