These are time-lagged processes. According to your version of things,
- $UNPLEASANT_JOB is costing too much! Let us start making robots
- Let us continue to bear the cost of paying $UNPLEASANT_JOB a high wage for the decade+ it takes to develop the automation for that task.
Nope, here is what will happen:
- $UNPLEASANT_JOB is costing too much! Let us figure out how to automate this task. In the meanwhile, let us dump the wages for this role. Otherwise, our company closes down.
- 10-15 years later, the same automation needs to be cheaper than the dumped wage for it to be feasible, which is a completely different challenge. First of all, the automation has to be cheaper than your "high enough wage", which is more than you can say for robotics products today.
