The fact that they rely heavily on robotics is noteworthy among Imperial worlds, but their robotics would be limited to "high data" basic learning systems requiring some human oversight; they are three tech levels away from autonomous systems.
First, that was a great post.
Second, an observation from the most recent Agricultural revolution: In 1800, feeding the people required over 80% of the workforce to be employed in agriculture. Today, it is approaching 1% of the workforce employed in some agricultural related career (and a lot less if you ignore all of the small marginal farms and focus on the big farms that produce 80% of the food supply.)
Manufacturing appears to be undergoing a similar 'revolution' with automation allowing a dramatic reduction in the workforce needed to manufacture everything that a society needs.
If we assume that by TL 9, the manufacturing and agricultural sectors will each have stabilized at about 1% of the workforce, then the old Paya of 12 million people would have had a workforce of 6 million which would have included 60,000 agricultural workers and 60,000 manufacturing workers to meet the manufacturing and food needs of 12 million people (
perhaps including the majority of the needs of the local starport and naval base). The current population of (
a few hundred to a thousand is a little vague for math, so let's set the current population at exactly 1000) 1000 would include a workforce of 500 and require only 5 farmers to meet its agricultural needs and 5 manufacturers to meet its general manufacturing needs (
excluding the wonder-infrastructure project). That leaves 490 surplus workers in the labor force. If they concentrate on manufacturing to support the 'dream', then the 495 manufacturing workers could oversee TL 9 automated factories capable of meeting the manufacturing needs of a population of 49,500 people.
Back when the world had 12 million people, it had factories to accommodate 60,000 workers/managers/technicians. Is it plausible that TL 9 robotics could have replaced many of those workers and reduced the need for humans from 60,000 to 6,000? Since the world has only 500 workers total and only 5 of them statistically want to work in manufacturing, I wonder if Paya could have used its wealth and contracts with the Navy Base and Starport to import the 6,000 manufacturing workers as 1,500 TL 12 autonomous robot workers? [
Note, a person works 40 hours per week and a robot can work up to 168 hours per week, so each autonomous robot replaces 4 human workers doing the exact same job at the exact same rate.].
I am just trying to bracket the range of possibilities:
At the absolute lowest end, 1000 people only need 5 farmers and 5 manufacturers to meet the food and goods needs of its people. That leaves 490 workers free to specialize in whatever the world wants.
Just above that, 1000 people could specialize in manufacturing with automated factories and have the industrial capacity of a population of 49,000 (or enough surplus industry to support 48,000 people worth of exports).
At the upper end, they could import 1500 TL 12 robotic 'supervisors' to manage 15,000 TL 9 robotic 'workers' to maintain the equivalent of the 60,000 person human manufacturing workforce needed to support a world of 12 million people ... maintaining the worlds original manufacturing capacity.
Like I said, my goal is just to offer upper and lower limits to 'what if'.
Take with a large grain of salt.
