Welcome Manna.
I'm quite the fan of the exocortex notion - the computer as an external brain that extends my intelligence, productivity, etc.
1. the Australia Project resembles the society in Ian Banks' series The Culture
2. Curious that a post-capitalist society uses credits to ensure allocation, sort of a UBI, but it seems to gloss over a couple details:
2a. Do credits accrue or is it use-it-or-lose-it?
2b. It sounds like credits can be transferred between people (the space elevator story), what stops credit accrual from skewing via the Pareto Law into the same 1% having 99% of credits?
