I don't think that the general idea is replacing specific jobs with robots. Probably not very pragmatic most of the time. Rather it's jobs that simply become obsolete due to technological advances.
You could probably eliminate the need for most firefighters by installing more and smarter networked sprinkler systems, using different materials for building, building smarter oven's / toasters / whatevers, or any number of other innovations... but all of that costs. It seems less threatening when viewed this way, instead of a robot replacement, but the effect is the same.
Automation is also elitist. I'm betting that a building housing Google's servers has more fire prevention capabilities and far less need of human firefighters than say a sweat shop in Bangladesh.
