Does not bode well for mankind/future generations. But they will know no difference.Ironically everything seems to drive us towards less self reliance. At one time we could make a wheel in the village from a tree in the wood. My great grandfather was the wheelwright. Now, as said, everything is reliant on shipping in items made by remote specialist mass manufacture, including the brains to keep it working. Even the taps in my bathroom now require specialist parts where the old ones could be repaired by a bog standard washer and seat regrinder.
