Play this scenario out. No internet for a month. No cell phone for a month. For everyone!

I would lose my superpowers and would return to reading books, running pen-and-paper role playing games, and playing single-player video games.

 

It has the potential of being quite bad. But I honestly don't think that it would send society to a screeching halt.
My first thought? The floor of the NYSE would become busy.

People would need to talk to each other in-person - interact in-person, and many communities would be strengthened from the increased interaction.

I do believe that it would absolutely change how people use technology, once the world regained connectivity.

I'm betting my husband's present job wouldn't change too much, he would just do more face-to-face negotiation, and probably play more golf. Now if he still had his old job, he would be screwed. Organizing logistics without internet connectivity is virtually impossible.

My present job... well, my daughter would still need me to potty train her, and she would still want to run around outside all day every day even in the rain... and I have enough papers and my data stored to the hard drive on my computer to continue working on my dissertation, I just would need access to a fax so my mentor and I could keep up with the edits. He is old school and would prefer to fax his scribbles on my papers anyway - he did that all the time until I asked that he scan and e-mail instead.

We live close enough to a branch of our bank that we could easily walk there and withdraw funds in-person, as long as the bank had their system in running order. But then again I wonder what I would want to spend my money on, aside from food, and honestly... the relatives we're living with right now have massive food storage so we could get by for a month with what they have on-hand.

I wouldn't want to own a business in this scenario. If I did, I would be tempted to close up shop and take a loss for that month.
