I don't know what you do for a living. But the odds are that at some point technology will find a way to make it less necessary. You will very likely become surplus to needs. And that will most likely happen when you are nearing the end of your working life. What do you do then?

So the issue is, what do you do with those people who no longer have a job? Can you afford to spend the money and years that might be required to retrain a, let's say a 50 year old truck driver for another job? And remember that not everyone can be retrained.

Start thinking beyond the end of your nose and look at the broader picture.
