"Here's a hint of what happens with new mediait's not world peace"
Um. Don't expect it to happen in less than several generations of people.
My view is that Radio and TV were unidirectional communication, from dictators to the masses, and enhanced the ability of fascist and communist empires to maintain themselves and fight each other. That's pretty much the sorry history of the 20th century.
Now we have peer to peer communication, and maybe the history of the 21st century will be the overthrow of dictators and the emergence of some sort of world peace. Or at least, a reduction in the scale and intensity of the wars. The fall of the USSR, and recent developments in the arab world, lend some support to this, but I don't expect to live long enough to see all the consequences of the internet played out.
