He concludes with -
All of the above seem to forget that technology does not implement itself. Technical knowledge needs people to implement it – people who have the right incentives to solve all of the glitches and unexpected problems that happen when you apply a new technology, people who make sure that all the right inputs get to the right places at the right time, and local people who are motivated to use the new technology. The field that addresses all these incentives is called economics.
Which is fair enough, but if you read the comments to his post you'll see that not everyone reading it agrees entirely. My thoughts aren't so much a disagreement as an observation that just as birds, bees and flowers don't need biologists in order to function, technologists don't need economists either. Sure scientists and engineers need incentives, just as priests and politicians do, but a detailed study of what incentives are most effective isn't needed. That's the great thing about markets.
Why hasn't Africa taken advantage of the technologies of the 20th and now 21st century? Beats me, perhaps it needs an economist to look into it. Though even I have a pretty good idea why the 1938 report wasn't acted on - http://en.wikipedia.org/wiki/Invasion_of_Poland_(1939) and the like.
