Recently a basic level of telepathy was achieved. It was possible to encode brain activity into a binary signal or file, email it far away and apply it to a receptor, who received the brain activity and reconstructed the original thought.
If thought can be encoded as brainwaves… Can’t we create a device, that using a machine learning algorithm, learns to recognize hate-thoughts and even, using the same technology in reverse, replace them? Eventually… We could ban from certain realms people that refuses to wear the device.
It would be a peaceful world. Because we won’t be really at control, anymore.
