In the future, artificial intelligence (AI) neural networks could evolve to the point of creating a technology that analyzes in real time, in a matter of seconds, whether news is true or not.
You can imagine this applied in a future where privacy has become an obsolete idea, where people recognize there is no way to progress technologically without massive data collection on everything and everyone. A complete digitization of the world, like smart dust.
So, imagine you are in a telepathic chat with someone in the 2050s or later. The user interface (UI) is controlled by thoughts and gestures and projected onto your optic nerve by neuronal nanobots (cortical modem), something like an augmented or mixed reality UI, where the semantic web would make the concept of URLs, websites, apps, and hyperlinks seem very last century, the same way we look at clunky computers in the 80s.
In this new age of context-aware computing, information would come straight to you.
So, real-time fact-checking would take place when you are communicating with someone; information would appear in a pop-up confirming or disproving what the other person is saying (or thought-sharing).
This would create a transhumanist reality where all aspects of life have algorithms, even in what we think we will never have, or simply disapprove of – truly life gamification.
Concern about fake news would reach a point where it is desirable to create a way for AI to read all forms of communication, including thoughts, and display online content based on the present moment, as if by magic, when in fact it is just sophisticated context-aware computing.
The values and morals of the future may be different from today. What we presently see as invasive may become something that makes things more controllable.
So, we will have a post-privacy society, which will still cause concerns about bad guys having access to data,, this time neurodata. The problem could be solved with things like quantum cryptography and DNA tokens.
But for everything to work the way it should, we'll still need the AI and a certain group of people to have access to this much more intimate data than anything companies collect on us today, and it would be a good thing if it's just a few people.
