Wow! Good question. I think we have come to rely on technology so much now that life would definitely be more difficult if we had to go back to the time before we had all this at our fingertips.
I was just thinking the other day how much things have changed even just with the mail. I had one bill that I was paying through the postal service, which is our water bill, simply because they do not have online bill pay. Everything else is online....so just that one task of paying bills would be so much more difficult!
Then thinking about the time I used to tell my husband, "...if I don't call you in an hour then come looking for me because you know I didn't make it" when I was driving alone somewhere....before cell phones!!! Just those little things we take for granted now.
Yes, life would be much different....
