Ya, I get your drift.
I’m an electrical engineer.
I stand by my statement.
It is useless going to a single user anytime in the forseeable future. Now it is useful for backbone communications. That’s where it is likely already in use.
It isn’t some magical breakthrough that is waiting for the future to catch up to. The connection speed is the easy part at those speeds. And yes fiber goes really fast and if your willing to dig up all your neigborhoods you can get fiber too. Not some new fantastic technology, simple economics.
Henry Ford did not come up with any new fantastic technology either (he didn't invent the automobile nor the internal combustion engine), but how different would American life have been if he had listened to the naysayers who told him that there was no point in building millions of autos when there were no roads or gas stations to accomodate them? (Luckily for us, he didn't listen.)
