Thanks for the comments.
Gerontocracy is pretty much the government system of ancient Sparta (without the immortality, the ephors were pretty much in charge, even if they had two kings)
That's true. What I am trying to capture here is that sci-fi "council of wise [or corrupt] elders" trope, with the view that adding biological immortality to the mix causes a qualitative change to how it functions. In practice, it will look most like a better version of Monarchy.
Machine Rule needs to be distinctive w.r.t. technocracy
There are similarities. Both are based on the notion that society should be run in a scientific, dispassionate manner. The main difference is that a technocracy, as envisioned by the mid-20th century technocracy movement, is run by engineers and experts who are human. Technocracy comes at Virtual Society, which is a bit early in the tech tree for AI to be in charge. Arguably, systems such as Soviet communism were at least attempts to implement technocratic government.
Also, Technocracy is a Government civic and Machine Rule is a Rule civic. To tell you the truth, I don't really understand the difference between the two.
Post-Scarcity is already a labor civic (although economic or welfare would probably fit better, and we already have civics with the same name, like vassalage)
The system is a little screwy now. The labor civic is actually called Post-Labor, though the autobuild civic building is called Post-Scarcity, and the XML tag is POST_SCARCITY. Since it becomes available at Androids, I think what it is really capturing is that automation has proceeded to the level where not much of the population needs to work anymore. That might not necessarily be a post-scarcity situation; one can imagine a scenario in which most of the world's population lives in poverty because they lack any meaningful economic opportunity.
Taken together, the set of Post-Labor, Post-Scarcity, Abundance, and Post-Currency form the utopian vision of a world in which economic problems are solved.
In welfare there is already Paradise and Superhuman
That's another funny situation. Paradise becomes available at Ecological Engineering, which is close to present day. I'm not sure exactly what it means, but I generally take it to be the social democratic vision of a society organized by the principles of environmental sustainability and human equity. Superhuman comes at Homo Superior, so I take it to be the idea that humans are genetically engineered to achieve better social outcomes. Abundance comes at Molecular Assembly (mid-Galactic) and is the idea of a very high level of material wealth as the basis of prosperity. See e.g. Neal Stephenson's The Diamond Age. So the three really are different things.
The general difficulty is that some of the civics and categories run together and it is hard to know where one stops and another begins.
Recycling sounds less futuristic than Off-Planet-Dumping
Recycling comes at the Recycling tech, and that's a fairly obvious place to put a civic. As for Off-Planet Dumping, I pushed that back to Coilgun and might push it farther. Today, the idea of disposing trash in space is not even close to feasible. It costs millions of dollars per ton to launch things into orbit, while it costs just a few hundred dollars per ton to recycle nearly everything using an state of the art facility. Landfilling, even with all proper lining and management, is cheaper but then we lose out on material. Even a plasma arc recycling system for disposing of hazardous waste, or tossing nuclear waste into deep oil or gas wells (or saving them for use at a Generation IV plant) makes far more sense than trying to launch this stuff into space.
Energy Currency needs to be separated from Digital Currency
Digital is a bit of an odd duck because in principle it is compatible with Gold Standard, Fiat, or Credit. There are really two policies here: one is how transactions are done, and the other is what underlies the value of money. With the Energy civic, I am thinking more toward the latter, and the civic is modeled after Gold Standard. The theory is that in the distant future, with vast amounts of energy coming from Dyson spheres, energy can be transformed into all other economic goods, including labor via computation, and so energy becomes the fundamental resource against which currency is measured.
