Well, this is possible, but it will take very few workers to produce the huge amount of goods to make it profitable. Case in point: e.g. a Novo Nordisk factory that produces like half of the EU supply of insulin employs like 15 workers per shift, who mostly oversee automation at work, handle incoming / outgoing trucks, and ensure physical security of the plant.
It's the same thing that happened to the US agriculture: in 1800, it used to employ like 80% of the population, in 2000, 2% to 3%. Machines replaced human labor almost fully.
