Two of the marvels of the modern age have directly impacted the developing world. One is the Green Revolution, using artificial fertilizer to dramatically increase crop yields and keep billions of people from starving. The earth is severely overpopulated, but mass starvation is not currently a problem.
The second marvel is how cellphone technology emerged at a moment that kept the developing world from having to spend billions and billions of dollars to build telephone landlines and other infrastructure. In Africa, Asia and South America cell towers and phones are making landlines redundant, if not obsolete.
This communication revolution made me wonder if another communication revolution that is the spawn of cell technology is an explanation for the Trump Phenomenon. Before Barack Obama, presidents communicated with their publics through traditional media: televised speeches, news conferences, press releases – all of it mediated by professional journalists. Obama was the first president to use social media, and he used it most effectively in his two election campaigns.
