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.
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.
