As a public manager of taxpayers' money, how can we make good decisions when we have time frames like the ones you mentioned, namely, 30, if not 50, years? Obviously, we make decisions based on the information available today, in 2012. If this was 2042, my children might perhaps choose something other than the previous technologies. It will always be difficult for government managers to make a decision for the next 50 years.
