Last year I was traveling and met Peter Bloom, a nice guy that coordinates Rhizomatica, a nonprofit organization that brings cell phones comunication to small village in Africa and Mexico.
Recently the Federal Telecommunication of Mexico approved to 5 states in Mexico to make use of the radio frequency in order to provide legally cell phone services to communities where Telmex is not willing to provide the service because of the size of those small villages and because they are not profitable.
Perhaps soon people using cryptographic technology will be able to interact in the telecommunication industry and disrupt the current monopoly worldwide. probably it will be within next few years? or could be sooner, or another surprise like Steemit!
