If there were a simulation, instead of being just one character, how about being eight billion simultaneously? Your consciousness would constantly alternate between every person in an infinitesimally small period of time, giving you the illusion that you are in the same individual continuously. Each person would have different memories, personality and context, and you would have no knowledge that your consciousness is living everywhere, in everyone.
Authoritarian governments will find it ever easier with technological advancements to zombify and control their populations. When such a government, helped by surveillance technologies and AI, is able to know what you are thinking and feeling, where you are and what you are doing, has control over all the information you receive, and knows your personality impulses precisely – what hope has anyone to escape from the hell constructed for them by the resident psychopaths? China is already a long way down this path, Russia is hurrying to this end too.
There must be a model of openness that prospers in democratic countries. The algorithms that will increasingly guide our lives should be open source and publicly reviewable. There needs to be better realtime checking of fakery, using methodology that is publicly available. There must be a culture and processes in place to ensure transparent, accountable decision-making.
The time window for getting this right is now and we may never get the chance again.
