It's a weird feeling to realize how we're all just hardware, and it might be possible to wake up someone who's "brain dead"/vegetative by LSD (the paper mentions how psychedelics affect this cortical electrodynamics, and as this old article[1] mentions the LSD).
Imagine someone flipping a switch (in the future where tech to control the electrodynamics exists) and you're awake and aware of your surroundings again.
