For Penrose's quantum consciousness hypothesis to be viable, quantum effects would need to survive in the human brain long enough for a neuron to fire, but the human brain fires extremely slowly, and even basic estimates show this timescale is insufficient for quantum effects to persist.

Evidence Quote

For Penrose's idea to make any sense, you'd have to have quantum effects survive in the human brain at least until a neuron has managed to fire and the human brain is ridiculously slow in its firing.
