I can`t agree a lot about disadvantage  of job decrease.  When some jobs disappear because of particular reason, other jobs will newly come out because of 'that reason'. So someone might lose his/her workplace, while another one gets his / her place to work. This means number of job won`t be reduced by the effect of replacement. It would be maintained like now or it could be increased in the opposite..

But I agree with the price problem of robots. It is true that robots are so expensive that medium-sized company can`t afford it. I think it`s one of the biggest problem of it , so I also used it in my assay.
