@Logos01 when does the founder era end? Also how expensive it is to build the our version of the crystal palace it looked rad as hell but we probably do an onei'll type station than what you're showing. It be cheaper to build and very easy to expand and build more connecting stations with the many designs of embedded the station on an asteroid for protection, expansion and other things.
You don't currently have the means to build even a small version of the Crystal Palace. The actual station in Cyberpunk is a tourist trap/transportation hub with a permanent residency of 5,000, mostly catering to the very affluent.
But it was also built by a society that had dozens of O'Neill Cylinders (smaller ones) in orbit. (Highrider nations.)
A full on O'Neill Cylinder is also right out. Even the smallest varieties -- that would still be cylinders as opposed to a Bishop Ring or Stanford Torus -- are just too massive in scale.
Meanwhile what you have now is the simplest design that could be deployed fairly safely. A free spinning frictionless seal that is also airtight is a technical nightmare to attempt but your people came up with an adequate solution based on ferromagnetic fluids.
And it needs to be simple because if it breaks down while people are up there, they won't have much time to get to emergency pods and hope for rescue.
The reason for counterweighted spin decks for example is that they can be ballasted easily to avoid acyclic mass distribution that could unseat the couplings. With a toroid/donut that has to connect with a central axis that's actually much harder because you are having to balance a plane rather than an axis.
There's also the fact that, again, everything you guys are doing is... well, the Crystal Palace I mentioned before has a permanent staff of 5,000 but took tens of thousands of workers to build. Your entire population is crossing the 800 people mark this upcoming turn.
So you gotta work with the scale of what you have.
As to when the Founding Era will end -- I have a few criteria in my head for what will trigger that. The first of which you guys are crossing this upcoming turn -- hitting your 4th Pop. That's just the first, and there are others.
So... soon(TM). OP will surely deliver <tumbleweed>.
