It seems as though each century there are always jobs that are no longer needed and replaced either by automation or lack of demand.

It's not often you need to call your local blacksmith anymore or more recently go to your local video store (think blockbuster).

Our economy is a miraculous mechanism that always seems to balance these things out, either by good planning or by mistake. So I don't know how the unskilled labour are going to find work and what type of work they will do in the future but what I do know is we have a mechanism for adjusting..in that the economic system. And for those left behind some countries better than others have a social security system to provide a safety net.

So I'm not so negative about the future, more efficient production through automation will ultimately lead to more wealth. Lets just hope this wealth is fairly distributed.
