What they're describing can also be thought of as resembling a phase transition, expressing nonlinear dynamics, and they are merely playing around with words like "critical". The brain also clearly resembles a distributed gain amplifier, and they are not accounting for quantum effects. In other words, the brain and all living organisms should also express Yin-Yang Push-Pull dynamics, that can be broken down to both humble efficiency and elegant simplicity, that are ultimately indivisible.

Their critical thinking doesn't include what's missing from this picture.
