Interesting thought. I think too that at one point there will be reputation based tokens. There's even a necessity for that given the advancements of technology. Soon enough (maybe already today?) it will be possible to perfectly fake video sequences, voices and possibly even externally control behaviour.

This means, that at one point it won't be possible to distinguish between reality, fake - and with the neural integration of networks to our brain also unwanted behaviour and surreality. What it will need then is a way to make sure in a fail save way, who somebody is, where this person has been, done and in the case of neural networking also how far that person has meddled with other peoples consciousness and reality and to what extend that person has done it himself or has been controlled by others.

The result of this will be something like a reputation token and it will determine, to what extend someone can be trusted with resources.

The downside of that scenario of course is that it is quite totalitarian in both the sense of the extent to which people will be subjected to algorithmic behaviour patterns and it will also open the gates of hell to alter and form character and behaviour structures on the most fundamental level.

I bet that in 30 years from now, we all will have some sort of a warning light system in our brains embedded like cars have it today. And these lights will give us a red flag when we are about to do something wrong. It will be just the other way around as it is today. Now we have debates about the negative effects of porn, violent games and movies. In the future we will have debates about what to prohibit in real life and what will be limited to the virtual world. Depending on what you have in going in your virtual world and what mechanisms you have installed to prevent imagination spill overs to the real world, you will get a reputation.

Scary and crazy, yes. But I believe our grandchildren will be very, very different from us.
