I think some people would rejoice.
Some would revert quickly to the world they once knew without an overpowering amount of technology.
Some would read a book.
Some would try to rebuild.
Some would be lost.
We would look to our own brains for information or other's instead of google.
People would begin to work collaboratively again.
I think we would find a way to adapt quickly, however I think the the biggest difference is generation based. I grew up in the middle of the burst of the internet, so I knew what it was to not have a computer, and I know what it is to have my job rely solely on a computer. I think the younger generation that has grown up with technology from the start will have a harder time adapting.
