True, a busy factory filled with lots of robotic production lines and a handful of managers, security guards and janitors would be a 100% improvement over a crumbling, abandoned factory full of rats and rusty patches where the steel presses once sat.
Its not going to bring back the thousands of decently paid operator's jobs for the masses, though, If you're not careful, the planners and implementers will telework from their $$$$/month Silicon Valley apartments, or move into the newly-gentrified part of town from out-of-state, over the heads of the locals.
This was all predicted back in the 80s with the rise of the microprocessor - the advent of globalisation and cheap human-operated manufacturing in countries with wildly different labour costs just put the march of the robots on hold for a while.
