at this point in time you need a job to pay rent and buy food (and, if you're american, have a chance at decent health insurance). for coders it's easy to find a job, for people without such "in-demand" skills maybe not so much.
so any retail or food service job replaced by a robot means one fewer job for someone who might need it. in a just world that would be great, the whole point of doing work should be so that we have to do less work, but that's not how society is structured now. an american barista who loses their job to a robot has more or less no safety net at this point. the only benefit in this story is more profit for whoever no longer has to pay a human when they can pay a robot less for the same job
