Ultra High Tech Campaigns
Given the discussion about TL 12 and lower campaigns, I'm curious if anyone has tried TL 20 and higher campaigns. There's a lot of newer space opera science fiction that operates at very high tech levels, which push the limits of Traveller and might call for a more abstract system. The work of Peter Watts and Alastair Reynolds would be an example.
At TL 20, societies are post scarcity, with the ability to print state of the art equipment at will. Minds can be uploaded and transferred between bodies, but the technology doesn't yet exist to copy or fork someone's mind. (According to Traveller5 Core Book 2, anyway) Matter teleportation exists, with the accompanying problems it causes, but grey goo type equipment would be balky and experimental. (though still possible) Ubiquitous AI is absolutely a possibility, and technology is likely to be defined less by what it can do than who it is.
How would you adapt Traveller to a very high tech post-scarcity setting? Character creation would likely be the area most impacted, since characters don't have to experience as many problems with aging or injury.
