I believe that most people have yet to appreciate how quickly changes will occur with Artificial Intelligence which is on the cusp of an exponential explosion of efficiency gains. It won't be long before AI machines are designing bette and more efficient machines themselves. While futurists may see only positive results of this explosion in innovation, the real people performing the jobs that will eventually be replaced will suffer hugely.

That's because the prevailing economic model rewards owners for efficiency gains. Eventually, even the will suffer as people try to survive on lower and lower incomes and can't buy the goods and services delivered by AI machines. So governments everywhere will have no choice but to intervene. 

There are those who say not to worry, other jobs will be created. Problem is the job destruction may significantly outpace the job creation process.
