depends on the people. u can use it to make our lives better , or otherwise make us more lazy.but now a days it's improving our lives more than damaging.
Oh for sure! People in bigger cities don't even like to walk anymore.. They drive.. and consequently they get fatter and diabetes.. Plus walking is fun and makes the day more enjoyable. Now that we have fast cars, we also build things further and further apart so the distances are longer and everythings just so much more impersonal. Oh well..
