This next invention will leave you happy we have Ethical AI. Brain-to-brain networks allow you to communicate via thoughts. At this point in time, up to three people can be connected to this network.
More of a first stage experiment rather than dystopian mind control, participants test the brain network by collaboratively playing a Tetris-style game.
The network itself relies on recording brain electrical activity, sending and receiving only simple “bits” data at a time, and flashing LED’s at different frequencies for participants to focus on. We’re not at telepathy levels quite yet.
