You're familiar with the Law of Unintended Consequences, right?
Think about the following...
Now, I don't see much in the way of POSITIVE consequences coming from getting government involved in broadband - except a massive increase in costs with little to no increase in capacity. (Competition drives improvement - if government mandates a certain mb/second rate, at a certain cost - then that's what'll we'll get, even if better may be available.)
Another thing that's not taken into account when someone goes "Well, THEY have this, why can't WE?" is that the examples used are geographically limited and/or heavily subsidized. It costs a lot more for to provide a service, hardware and maintenance infrastructure to cover a few million square miles, for example, than an area the size of South Korea, Taiwan, or Sweden.
So what could possibly go wrong? (Yeah, silly question, right?)
Now, in the case of the Mars Rovers - unintended consequences have been VERY beneficial. The Pathfinder probe was the first attempt at 'soft' landing by means of airbag, and lasted quite a while. Lessons from THAT one went into the making of the Mars Rovers - and THAT pair have lasted a LOT longer than ever expected, despite (or perhaps?) being made as cheaply as possible. ('Cheap' being very relative, of course.)
The third one - that's interesting. It's not often you see an 'obsolete' technology ressurected like this. The advent of digital photography has really, really caused a lot of trouble for the traditional film makers - and in some cases (like Kodak and Fuji) they've managed to transition from providing film-based services as a mainstay to mainly digital cameras and services with film as a minor sideline. So what will the unanticipated side effects or benefits be on this product? Will we be seeing more 'obsolete' tech pop back up in the future?
Ah, such interesting times!
