There’s been a never ending debate on the greatness of the two.  Tesla, being the futuristic, visionary of the two, while Edison, being the more practical, business minded. 

One capable of true disruptive innovations, way ahead of the time, with little traction; while the other, with a more practical approach, solving problems at hand, building/buying product(s) that leave a huge impact in the intermediate future; capable of producing a revenue stream. 

As I ponder on the components that go into building great products, the kind of products that leave a lasting impact, disrupt the industry, and are vehicles of change.. I can't help but think of these two innovators. Finding the sweet spot between the two approaches; between the two kinds of brilliance.
