The only disadvantage that the consumer will encounter is cost, but that is at the initial setup. Once everyone implements FTTH then the market/competition will bring prices down, especially if municipalities get involved (see
Chattanooga TN)
The advantages are
everything else, the number one being less time waiting for something to complete equating to more minutes/hours saved in a day.
Not everyone's situation is the same - it would be altruistic and a human benefit to have a level field of performance for everyone at maximum (e.g.1000+/1000+).
I don't know if this analogy (see below) makes sense or not. but if we could build faster and shorter information delivery infrastructure paths then we literally,
on a macro level,
save years... From the movie Margin Call:
Eric Dale: Do you know I built a bridge once?
Will Emerson : Sorry?
Eric Dale : A bridge.
Will Emerson : No, I didn't know that.
Eric Dale : I was an engineer by trade.
Will Emerson : Hmmm... hmmm
Eric Dale : It went from Dilles Bottom, Ohio to Moundsville, West Virginia. It spanned nine hundred and twelve feet above the Ohio River. Twelve thousand people used this thing a day. And it cut out thirty-five miles of driving each way between Wheeling and New Martinsville. That's a combined 847,000 miles of driving a day. Or 25,410,000 miles a month. And 304,920,000 miles a year. Saved. Now I completed that project in 1986, that's twenty-two years ago. So over the life of that one bridge, that's 6,708,240,000 miles that haven't had to be driven. At, what, let's say fifty miles an hour. So that's, what, 134,165,800 hours, or 559,020 days. So that one little bridge has saved the people of those communities a combined 1,531 years of their lives not wasted in a fucking car. One thousand five hundred and thirty-one years.
