I expect they will need *some* human staff to just make sure nothing goes wrong. For example, if a piece breaks, someone will need to come in and replace it, ideally with someone on hand. There might only be a dozen staff in the entire building but I think at this stage we still need a few bodies there.
Also, what are those people going to do once the fans don't need bodies to work them anymore? It's a great idea in theory but then you'll have tens of not hundreds of thousands of people out of a job. If this was like Star Trek, they'd be free to pursue leisure activities or whereever their interests took them... but we're not there yet.
