The entire theme of his post was the argument that it will take a long time before we can enjoy those speeds. His supporting arguments included the opinion that most people don't NEED more bandwidth. So without the demand, it won't happen as soon as one may think. He even stated that he is excited to see such a prospect, but that he doesn't think he'll see it in the next 5 years.
I happen to agree with infinite in how MOST people don't need more bandwidth. Snappy email, great page load times. What we have is fine... for most people.
Sometimes you gotta read a post a couple times to get a good judgement on what a guy actually meant.
