A perennial fence-sitter, me.
I have a lot of time and energy invested in understanding comms protocols - so I find all the stuff behind VDSL2, vectoring and G.fast fascinating. But sometimes that fascination makes it look like I'm massively "pro" for the rollout of these. I'm not really - full fibre would indeed be much better - so it pays to understand the economics. I don't think enough pay attention to the economics.
However, I only have a "reasonable" understanding of the economics driving all this - just enough to be dangerous?
Where my understanding is lacking is in the quasi-artificial impacts of regulation, and the strange impacts there.
