Also, bandwidth gets made to satisfy demand. It will continue to grow in the world. Already in my life, it has gone from zero (no personal computers or personal-computer networks), to using phone lines starting at 300 bits/second then over a couple of years up to 56k bps, then to DSL up to about the 1 Mbps range, then cable modems starting from several times that up to 10's of times that, then to cable modems and fios-type stuff.
So, late 1980's to now, bandwidth I use in my residence went up by a factor of 300,000, and cost went down by a factor of more than that, and despite me getting a gigantically better deal, companies were able to make $billions in providing it, and workers made livings providing it.
It's been great all the way around, and there is nothing (other than regulation) that can kill continued progress in this area.
