Many people were saying this, Paul Krugman (one of the leading economists) went as far as comparing the internet to the fax machine:
"The growth of the Internet will slow drastically, as the flaw in 'Metcalfe's law'–which states that the number of potential connections in a network is proportional to the square of the number of participants–becomes apparent: most people have nothing to say to each other! By 2005 or so, it will become clear that the Internet's impact on the economy has been no greater than the fax machine's."
> You said it yourself - you're too young to actually know a lot about that, but you use it to bolster your arguments anyway.
I'm too young to live through it, but luckily I studied it in university :-) Many people claim to know many things about history prior to their birth. I guess I'm one of these people.
