In a post on newteevee.com, Allan Leinwand posits that infinite bandwidth is possible.

Er, what?

I have often found that people who talk about infinite bandwidth lack a basic understanding of what bandwidth is.

Like you, good sir, who seems to think that its possible.

We can expect to see bandwidth increase to the point where almost any application you can think of will not be limited by the bandwidth either in the transit networks or in the last mile, but the available capacity will always be finite.

And bandwidth providers will always differentiate themselves based on the size of that bandwidth.
