Nice! but... are these graph steps roughly at scale e.g. area of initial blue circle compared to all of human knowledge circle? or the small PhD pimple compared to the blue circle?

If not then can someone (original author or someone else) try to review the steps with roughly realistic average scales assuming surface represent knowledge volume and color complexity spectrum from advanced (indigo) to advanced (red)?

Any candidate to make another pimple on the outer circle?
