The world is flattening

There seem to be two contradicting opinion/school of thought about globalisation. One if the famous argument put forward by Thomas L. Friedman that the world is flat and the other argument that the world is not flat. Instead of religiously following a specific thought school, in this blog I decide to take a factual approach to this commonly addressed debate.
Now for the school that advocates that the world is flat - this school cites the new mobility of workers happening globally, increased outsourcing, offshoring, increased information technology adoption, access to information for all people, disintegration of the value chain globally and performing the value addition where it could be done best ( global search for optimal competence) as attributes suggest that the world is flat.
The world is not flat - this can be argued by a series of questions - why are the differences between the rich and the poor still very high? Why are innovations mostly still taking place in the silicon valley? Why are cities like Frankfurt, Hong kong, New York and London still in the height of activity than others? Why is agriculture still not globalised and integrated across economies?. Disparities between economies in terms of population, innovation, electricity, etc point to the direction that the world is not flat in fact it is argued as being spiky.

The truth lies somewhere in between - simply termed as the world is in the process of getting flattened at a faster pace than ever before, however we have still not reached there (The world being flat) and we will never reach there also.
