How has society been changed by technology?

We rely on technology more than ever. Less paper has been used. Technology allows us to do work even when at home. It has simplified access to education, transportation, communication, etc...

Technology also reduces time it takes to perform tasks. Even technology does our tasks for us, but that's not always a good thing. Technology has made humans more lazy and less active.
