It seems to me that you overestimate the cost of people making all that happen currently, and underestimate the difficulty of automating it (and maintain that automation). A lot of work isn't impossible to automate, it's just not worth the cost. Lots of people unfortunately earn very low salaries, they're cheaper than a machine. This is the case both in manufacturing, and administration.
