I will agree that addressing deficiencies in the market often lends itself to opportunity and profit, but I do not think it’s apples-to-apples to equate a reservation app to a virtual doctor app in terms of equal opportunity. Consider the fact that there is more overhead with virtual medical assistance — not just in terms of the complexity of data, but in terms of liability. A tech company is not going to be sued and wiped out when someone misses dinner, but they will be if it’s demonstrated their app gave information resulting in injury or death.
I will agree, wholeheartedly, with your idea that social impact is a vital tool for inspiration. Particularly in societies void of depth. Very few leaders have the vision or the fortitude to lead beyond the guidance of their board of directors and their own pocketbooks.
