I've said it before to the naive idiots entranced by Labor's proposal for the National Broadband Network, and I'll say it again - technology is racing ahead so fast from so many different directions that anything built by government is almost certainly going to be obsolete before it is even built.
The days of massive government infrastructure projects like the installation of the copper wire network belong in the last century. The pace of change back then, being so much slower, made these projects sensible even given the natural inefficiency of government bureaucracy.
Not today. Not in the 21st Century.
