I agree with you. But probably this future is unavoidable. A company selling robots only for dangerous jobs would never be profitable. If you stop this current development, you need to stop capitalism. I don´t like it but is there a better choice? If e.g. one country creates restrictive laws against robots, the companies will go to other markets.
BTW, lawn mowing robots are in place since years already. For this you don´t need an humanoid shape.
