This a thing that needs to be more widely known. If you saying, as people here sometimes do, "oh but my new tech could help people move money in poor parts of the world" (not mentioning any specific tech right now) and you're not familiar with M-PESA, then you're just out of your depth and talking foolishly. The real world has already moved past you.
