...Hmm, I wonder... Can McDonalds replace 95% of their workforce with machines?
I'll take that as a rhetorical question...

Not really

The meat patties are just frozen disks of meat, so devising a machine to cook those in a JIT principle would be better than the way it's currently done. Creating sandwiches is merely selecting the right bun, adding meat, and combining different variations of ingredients. If machines can do all that and customers can place their own orders, then there is little need for the cooks and cashiers. All you need is a person to keep the machine stocked on raw ingredients -- which would eliminate about 95% of the labor.
