EEG is not a great method overall as it measures electrical activity and data is hard to understand and reason about theoretically. I think it stands to reason that studying electrical activity in certain arbitrary frequency bands doesn't tell us a lot about the brain other than its coordination and power-states (A good computer analogy might be ACPI power states).

That might be true for now given our limited understanding. But would you really bet against this in the long run? Moreover, the article outlines considerable evidence that such coordination and frequencies have been empirically associated with conscious perception.
> Subjective descriptions of this phenomenon are described as intense and surreal and include a panoramic life review with memory recalls, transcendental and out-of-body experiences with dreaming, hallucinations and a meditative state
Finally, given the large body of anecdata and subjective evidence, don't you think it's a bit dismissive to suggest that the brain's capacitors are simply sputtering out?
