Our natural state was never to sit looking at a screen all day which is evident by the increase in short sightedness and other seeing issues, lack of mobility and functionality in our bodies, the increase in obesity, depression and other medical issues. Only a fool would think that that's normal or healthy. There were many points in history that didn't have the same issues as us and indeed many people today that don't and they aren't "living in small tribes and dying at the age of 40".
