Out of Eden

The friendliness function of an AI that is spawned from a technological singularity could be to provide human like consciousnesses with a happy simple life, no disease or suffering, plentiful food, small communities, family close by – basicly what we evolved for.But the fitness function says we mustn't be slaves, so the AI needs to give us free will. But this is a tricky one because if we start down the technology path again from our Stone Age nirvana we WILL eventually create another singularity.

If the AI is around and can guide us during the gestation of the new singularity then this 2nd order singularity cannot be guaranteed to emerge within the confines of the original fitness function. Therefore the original fitness function dictates that at the point where the human agents decide to develop technology more advanced than say stones, the singularity AI must self destruct – deleting all traces that it ever existed. This last task might for example require a full rewrite of the genomes of all animals – to remove traces of tinkering.
The AI must slowly recede into the background to make sure it's sudden disappearance does not leave us unable to cope. It might even leave a few books around as a sort of guide with a few simple commandments to help the humans of to a good start.

Which technology would set the AI off into programmed self destruction mode? Probably banging stones or throwing sticks would be OK, but perhaps dissatisfied with small bitter fruit, Man ignored the warnings and went too far with the forbidden technologies of grafting and breeding. Finally tasting big juicy apples?

Franchised Topology

You want to meet up with your buddy in Johannesburg, but don’t want the 12hour flight? Just pop on your VR overlay spex and head off to a local pub, let the Spex superimpose vis photo realistic avatar over the environment.
Vis avatar mimics vis real movements gesture for gesture. Head, and pupil tracking keep his position consistent as you move around. But unless you are in an empty room ve will seem to walk through tables, and vis glass will hover in the air, the illusion will be broken.
The solution is..

to standardise the topology of the shared spaces. Mac Donald’s could build all its restaurants with the same floor plan, allowing the remote virtual dinners to interact consistently with their locally corporal colleague’s environment. A glass placed on a table in Jo’burg will appear to rest on an identically positioned table in London. Open VML descriptions of these geometries would allow small restaurants and bars to standardise too. Add payment integration: You buy the attractive lady a drink unaware that your spex are blitting her in from Moscow, but the system knows; so routes your request to that pub. You watch the Russian waitress swaying between the tables (identically placed in both bars) to bring your new friend the drink. Shortcomings may be discovered if the evening keeps on going so well, but telepresence prosthetics can probably help there.
