NBN fibre to the premises - what are the real costs, benefits and value?

Indeed, but the NBN is the subject of this topic.
[edit]
The others would be off-topic.

Is that how it was done before? I’ll be interested to see your substantiation.

But you’re right, training is part of the opportunity. There’s work in training workers. There’s work in training the trainers.

As mentioned elsewhere:

Telecommunications infrastructure is, as you point out, one opportunity. There are real benefits there. Some may recoil in terror of the complexity, but we’ve done complicated things before. Are they now beyond us?

My guess is that we’re in for a long period of recession, if not depression. It may well be that Capitalism is past it best-before date. Either way, we’ll need long-term projects to tide us over while the new order (whatever that proves to be) establishes and stabilises. FttP is one such project (bearing in mind the multi-generational service life).
