"What are we so dependent on that we have lost our ability to do without?" Without cheap oil and natural gas our societies would be in chaos. Oil is the feedstock for almost everything we use and consume (either directly or indirectly) as well as the fuel for almost all of our vehicles. Without natural gas most of us would starve because it's the basis of artificial fertilizers.

Although a computer is part of handling big data, I can manage a lot of situations without a PC. Even with a PC, there are lots of judgement calls that are pencil and paper experiences, or even waving of arms. A few weeks ago, however, I had a real issue. No pencil sharpeners! So that's my current dependency. Tom.

There is an old saying. "What one has to do without, There is no good in thinking more about." We are evolution, we are about finding another way, if we do not have a bridge, we will use a boat, no boat, we swim. In short, if our attitudes are right there is nothing we can't do without.
