This 'story' has been repeated every couple of years since the internet started.
Ooh, we can't possibly have PICTURES, the network will collapse.
Oooh, we can't possibly have MUSIC, the network will collapse.
Oooh, we can't possibly have VIDEO, the network will collapse.
Oooh, we can't possibly STREAM VIDEO, the network will collapse.
Oh and then the stuff about running out of IP addresses.
Etc.
