Edges and intersections are always more interesting. This is true across multiple domains. Coastlines, roads, music, business and academic fields to name a few.

Starting a business that relies on the edge of the frontier raises the stakes, higher risk and higher reward.

If you guess right that the market is going this direction you can get a head start on defining the new direction and you have little or no competition. However, it is very difficult to get all of the following right: technology, general market direction, timing of readiness to accept a new technology or process, brand desirability/acceptance and willingness to spend money on your innovation.

I have done some arguably cool innovative things at the edge. But here I am still selling my time. It is really tough to get them all correct.
