Our minds do operates internally much faster than our mouths or fingers.

The speed we go from thought to thought internally is lighting, compared to how fast we operate when we have to update the subjects of these thoughts on pen and paper. Or explain every step of our thinking, as we make it, to someone else verbally.

Our brain is far more densly connected and faster operating than brain signals sent to direct a physical arm and hand, pen, paper, back through the visual system.

Being able to adjust any stable visualization in the mind by just visualizing the change to instant effect, removes mental friction and increases internal bandwidth.

Any removal of friction or increased bandwidth to thinking is profound.

Slowed more careful thinking, and slower collaborative thinking, are often helpful. But being slowed down by limitations is never a help.
