Dear Oscar, 
You mention the "fourth industrial revolution and its impending major trends", but you don't tell us what any of that means. Could you explain? As far as I can see, we in South Africa have barely embarked upon the "Third Industrial Revolution" (see Jeremy Rifkin's book by that title). For anyone who wants to know, Rifkin argues that "the great economic revolutions in history occur when new communication technologies converge with new energy systems". With that in mind, it is clear that South Africa is still firmly stuck in the second industrial era because we still predominantly use oil combustion engines and rely on centralized power. We have a long way to go down here, and really we are in no danger of robots replacing any level of skilled labour any time soon.
