You just went to the Google homepage. What actually happened?
You just pressed a key on your keyboad.<p>Simple, isn't it?<p>What just actually happened?<p>You engaged a cascade of motor neurons to coordinate the contraction of thousands of muscle cells, which pulls a lever attached to your calcium crystalline framework, grinds across a glucosamine joint. This forces your calcium crystalline frame-member to depress, compressing your saline-filled lipid-polymer foam skin against the keyboard. As you do this, you constantly measure the pressure against the lipid-polymer walls to ensure you are not deforming your muscle cells too much or too little.<p>---<p>Reality has inordinate complexity. When humans build roads or build narratives or build websites, we are simplifying reality for ourselves and others, including other animals.
