Question:

What is the most important invention in our life ?

Best Answer - Chosen by Asker:

100 years ago people had no access to instant information (No radio, no tv, no internet). The most important invention(s) are those that have created instant access to information. I don't think that we as a species have begun to understand the long term impacts of this. There are positives, for sure, and there are negatives as well. There are probably long term (not in our lifetimes) evolutionary consequences as our brains and bodies change to process more information more effectively, with less physical exercise and exertion.
