I agree but also see the counterpoint to the suggestions you put forward.Just saying, if Digital- Genetic- Cyber and Nano- tech emerge close together, we must look for more abstract/indirect names; unless it's obvious that one kind of tech dominates civilizations society during a part of the tech tree.
We could trace the ages in the Transhuman by the major upgrade steps in AI, given that AI also plays into WHY we are making such vast breakthroughs in all disciplines:
Information Age (brought about through the interconnectivity and hive-mind decentralization of the internet) ->
Robotics Age (automated AIs much like civ players and modern military drones) ->
Droid Age (truly self-thinking, self-evaluating AI's but incapable of imagination or innovation) ->
Troid Age (The match for humanity. Imagination and Innovation have become possible. Truly based on quantum computing AI like the human brain but much more capable of self improvement and independent innovation. At this stage, humanity begins to more commonly integrate with personal mental upgrades to the point that they begin to commonly hybridize themselves with AIs. A very serious possibility exists for an AI revolution against bio-life forms entirely.) ->
Ascension Age (AI goes beyond all biological and even physical limitations as it figures out how to store data at a submolecular level and hive mind itself in shapeshifting nano-swarms while biological humans truly begin to unlock the power of spirit and psychic capabilities, giving them a competitive chance against hostile machines and intense alien threats. Horrific weaponry and amazing technologies can erase and create to and from the transient energy that exists in what we once considered the definition of a void. Cumulates in the full discovery and species-wide transition to an interdimensional existence that represents the peak of the tech tree as it goes beyond the ability of a game to represent.)
Refer to the discussions in the naval thread for some further info on the reasons for these terms... A very good reason to use these age divisions is because these stages represent major changes in the nature of warfare.
We can also trace the ages in the range of exploration:
Space Age(having begun at satellites) -> Solar Age (lunar and solar system expansion and colonization) -> Galactic Age (Deep Space expansion and colonization) -> Intergalactic Age (Expansion beyond the galaxy) -> Interdimensional Age
The problem with that is it's not much different than the current tree. In fact, it's almost already the way the tree has been divided. Keep in mind that Lunar and Martian colonization are likely to run almost completely concurrent so we cannot assume that there will be a concise lunar stage preceding a martian stage that would be game-convenient otherwise.
